When a fat person walks in front of you and and you can't stop staring at that random skin flap that is on both ass cheeks that makes it look like they have four ass cheeks.
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.
