Butt plunging is Briana Bank's favorite position!

butt-plugging 

behaving like an idiot.
talking incoherently, replacing most word with different slurs(usually accompanied by exposing parts of the body that nobody wants to see\touch\smell), and being an ass in general.

guy: "man, I should really stop smoking pot"
butt-plugging guy: "dude,dude,dude,dude...I gotta stop with the pot...pot, pot, pot...I need pussy, pussy, pussy, pussy... gotta replace the drugs with the pussy!!!" ~exposes penis~
