Mickey Mousin'

To have an erection so incredibly large in public that you need to excuse yourself to the restroom.

Jim: Excuse me fellas, I gotta go to the bathroom cuz I'm Mickey Mousin' over here!
Phil: TMI, Jim...

Mickey Mousin'

(similar to daffyducking ) When you are giving a girl oral sex and you then take a rodent, preferably a mouse, and push it into the said girl's vaginal tunnel. This then causes severe orgasms.

Dum ass dude 1 : Yo, me and my girl were daffyducking last night
Dum ass dude 2 : That aint got nothin' on me and my girl, we went mickey mousin'
