Slap ass Friday first originated from schools in Washington state, Basically any Friday of the year teens/kids/classmates will roam the hallways slapping any ass they see while saying "Slap ass Friday!" Generally guys will make this as an excuse to slap women's asses. Girls can slap guy's asses too, girls can slap girls asses, guys can slap guys asses. This Friday has been going on for seven years.
Guy: *slaps girl's ass*
Guy: "slap ass Friday!"
Girl: "you fucking jerk! Hmm well I guess it's okay cuz it's Friday
Guy: "slap ass Friday!"
Girl: "you fucking jerk! Hmm well I guess it's okay cuz it's Friday

The Friday of every single week all school year where students sexually harass other students by slapping each other's asses without consent. Students and teachers at the time don't even realize it's sexual harassment because of Rape culture in our society. All in all it's literally normalizing the sexual harassment and reducing the education of personal space and boundaries.
Sally: Oh my god! I totally just got my ass slapped by some random person today!
John: You do realize that's sexual harassment, right?
Sally: NO! THEY TOLD ME IT'S SLAP ASS FRIDAY, It's like an actual thing now.
John: I'm pretty sure that's sexual harassment, Sally! That's not okay at all.
John: You do realize that's sexual harassment, right?
Sally: NO! THEY TOLD ME IT'S SLAP ASS FRIDAY, It's like an actual thing now.
John: I'm pretty sure that's sexual harassment, Sally! That's not okay at all.

Slap ass Friday shouldn't be real, It's sexual assault.
If anyone is touching you talk to someone you trust.
Kids, never do this please. This is sexual assault.
