An excuse made by teenage boys to sexually assault teenage girls in school hallways. This causes girls to hang their backpacks down low to cover their ass so that boys won't hit them. Nobody likes this except the perverted boys who participate and there are never any repercussions.
Boy: *slaps girls' asses in the hallway*
Girl: You can't do that. That's literally sexual assault.
Boy: Yes, I can! It's Slap Ass Friday!
Girl: You can't do that. That's literally sexual assault.

Get the Ass Baconmug. Ass whisper is when you fart and instead of it being loud and like someone screaming and it’s just a gentle breeze and it feels like it’s whispering.
Person 1: who farted
Person 2: I don’t know I didn’t hear it
Person 1: oh, then it must be an ass whisper
Person 2: I don’t know I didn’t hear it
Person 1: oh, then it must be an ass whisper
