Assflak 

When a hobo shits all over an Office Depot bathroom stall. With shit smeared all over the walls of said stall. Can be done in combination of ass spackling. Must be pronounced like the duck from the aflack commercials. If not pronounced this way one will just sound silly.

Dude! I think that hobo just assflaked all over our fucking bathroom.
