I saw a kid wearing a Hentai Haven hoodie in public a month ago and had this exact dilemma.

Not me when I was a teacher. "Hentai shirt is inappropriate for school. You get to change shirts. Next time go all out and wear an ahegao shirt if you want to be sent home."

That's kinda genius. They can't punish you without admitting they know what the thing is... That's kinda a... Hentai Paradox!

You don't type Hentai in Google and just shop around.

Writing him up is not a sufficient enough punishment

A guy in HS got in trouble for wearing a shirt that said "The more the merrier," with a silhouette of a lady wearing a Santa hat. The teacher said "I know what that means, it means you're trying to have sex!" in the most triumphant tone.

Ok I thought the article was just gonna be some silly thing but holy fuck it's amazing lmao.

I’m vaguely reminded of the episode of Cash Cab where the guy says to Ben, “Hentai” instead of “Henna’l causing Ben to pause before claiming his answer was incorrect.
