What is the meanest thing you ever done to someone ?

peed on my parents tooth brush as revenge

When I was younger I uploaded some photos of my old best friend and her ex on Facebook because she was dating my crush and I was jealous and spiteful and very immature. Lol.

In school planted cheat sheet to a big exam, on a girl for playing with my emotions, may not sound like big thing but she got dropped from national honor society and other honors revoked

as a kid, I filled the bristles of my brother's tooth brush with tooth pain medication. His whole mouth, tongue, lips etc went totally numb

Liquid Crab Boil mixed with water, ice cubes added, looks Exactly like Iced Tea.

Turns out to be [u]NOT a very funny[/u] April Fool's Day joke!

Jab my thumb into their eyes take their wallet then fuck their girlfriend

Can't say in the open but it's so fucked up and disgusting, you'd be angry..

I don't wanna sayyy lol

Do you mean, done to someone today?
