A dirty arvin is a prank, which is acted out, when you take a shit and put it in a "Karen's" pillowcase. It can be any Karen you want it to be, as long as the shit is taken in the pillow she regularly sleeps in.
Person 1: Yo dude! Guess what I just did!
Person 2: Well, I saw you coming from Karen's room, so I am guessing...
Person 1: Damn right my nigga, i pulled off a dirty arvin!!

When you get with your best friend's ex then take them in car rides to leisure centre car parks. You cum in her mouth, clamp it shut tell her you have an STD, and your baby juice comes flying out her nose. Take out your competition by letting them crash their car while going 'under' the speed limit.
