buttbuddyvone 

A shifty and often shady asian male (female is buttbuddyvona). Buttbuddyvone often has a poor grasp of the English language, particularly plurals. His whereabouts are difficult to pin down, though he may be making the errand or hunting for sideways vaginas.

Buttbuddyvone, you are a shifty, shady little bastard.
