It's when a guy who talks in Mickey Mouse's voice and goes behind complete strangers to give them a reach around.
My gay roommate just went batshit crazy at Disneyland and performed a dozen dirty Arvins in an hour.

A dirty arvin is a prank, which is acted out when you take a shit in a random "Karen's" pillowcase. It can be any Karen in the world, as long as you take the shit in the pillowcase she regularly uses.
Person 1: 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 nigga, I pulled off a dirty arvin!
Person 2: Well, I saw you coming from Karen's room, so I am guessing...
Person 1: Damn right nigga, I pulled off a dirty arvin!
