Fuckle

Fuckle is your microscopic buddy after you sexy time with your girlfriend. The "Fuckle" prefers to be named Mike Hawk Jr., but you can substitute it with My Penis II. It has been told in legends that people who reject their Fuckle Buddy die a very gruesome death that includes being castrated and learning how to ride a bike.

Guy: Hey what's that on the bed?
Girl: I don't know but I can feel it licking my anus
Guy: It's my fuckle buddy!
