Koolaid 

To face your thumb down and insert it straight into your girlfriend/boyfriends butthole, rotating in a circular motion- almost as if you were stirring a pitcher of koolaid- while simultaneously saying "OHHHHH YEAAAAAAHHH"

BF: hey babe I'm horny let's do something freaky

GF: wanna koolaid me?

BF: huh?
