"Similar to the 5-inch inseam short craze that took over the video-sharing app in the summer of 2020..."

"... TikTok users are now getting all hot and bothered over men sporting another simple, unpretentious piece of garb: the backwards baseball cap. In a recent viral trend, users are sharing videos of their boyfriends and husbands in baseball caps backed by the popular TikTok sound called 'I like you have a cupcakke,' which is used to share a user’s personal preferences. The format goes like this: words flash across the screen indicating things that a user likes as a child’s voice repeats the words, 'I like you, have a cupcake.' Then, abruptly, the sound is interrupted by the rapper Cupcakke’s song 'Vagina,' at which point a final phrase appears on the screen, this time indicating the thing the user likes most of all, trumping all else. In the baseball hat videos, women film their significant others wearing normal, forward-facing caps and then no caps... then...  wearing their caps backwards."

 
From "The Hottest Way to Wear Your Baseball Cap? Backwards. A recent TikTok trend highlights the enduring sex appeal of backwards baseball caps" (Inside Hook).

The relevant TikTok videos are embedded at the link, so I won't put them here. I don't know if I noticed the shorts craze last summer. Maybe not. Was I using TikTok then? It's something I like to look at these days. But whatever. I had never heard of the rapper Cupcakke, nor of the song "Vagina," which sounds rather obvious, but I will read the lyrics. 

Okay. I've accomplished the task I assigned myself. I was surprised to see that it was by a woman. Isn't that weird? I thought a man was contemplating the mysterious genitalia of the other, but it turns out Cupcakke is female, and it's another one of those songs bragging about one's own genitalia. And really, it's absolutely mere chance that I've got 2 posts in a row with prominent genitalia.

As for hats... did you know that Freud thought hats were a phallic symbol? From "The Intepretation of Dreams":

1. The hat as the symbol of a man (of the male genitals): 

(A fragment from the dream of a young woman who suffered from agoraphobia as the result of her fear of temptation.) - 

I am walking in the street in summer; I am wearing a straw hat of peculiar shape, the middle piece of which is bent upwards, while the side pieces hang downwards (here the description hesitates), and in such a fashion that one hangs lower than the other. I am cheerful and in a confident mood, and as I pass a number of young officers I think to myself: You can't do anything to me. 

As she could produce no associations to the hat, I said to her: "The hat is really a male genital organ, with its raised middle piece and the two downward-hanging side pieces." It is perhaps peculiar that her hat should be supposed to be a man, but after all one says: Unter die Haube kommen (to get under the cap) when we mean: to get married. I intentionally refrained from interpreting the details concerning the unequal dependence of the two side pieces, although the determination of just such details must point the way to the interpretation. I went on to say that if, therefore, she had a husband with such splendid genitals she would not have to fear the officers; that is, she would have nothing to wish from them, for it was essentially her temptation - phantasies which prevented her from going about unprotected and unaccompanied. This last explanation of her anxiety I had already been able to give her repeatedly on the basis of other material. 

It is quite remarkable how the dreamer behaved after this interpretation. She withdrew her description of the hat and would not admit that she had said that the two side pieces were hanging down. I was, however, too sure of what I had heard to allow myself to be misled, and so I insisted that she did say it. She was quiet for a while, and then found the courage to ask why it was that one of her husband's testicles was lower than the other, and whether it was the same with all men. With this the peculiar detail of the hat was explained, and the whole interpretation was accepted by her. 

The hat symbol was familiar to me long before the patient related this dream. From other but less transparent cases I believed that I might assume the hat could also stand for the female genitals.

If it is true — and who believes Freud anymore? — that the hat symbolizes male (or female) genitalia, what does it mean to put your hat on backwards? You can connect the dots. What do dots symbolize?! I'll just say that a ball cap — hmm, ball cap — has a visor for a very functional reason, to shade your eyes. If you turn it around backwards, you're losing the functionality. 

Anyway, I think those TikTok videos about short shorts and backwards hats are satire! It's not serious advice about how to look sexy, and if you fall for it, that's just another data point in the larger picture of how unsexy you are.
