Fassy Kisser 

The definition varies; just ask the holy lord and savior of the Capetian Dynasty and Han Dynasty. It’s the ultimate insult that can only be used every half life and destroys people’s career.

Nick: You are a FASSY KISSER!
Sean: No, Nick you’ve ruined me.

Hey, Michael Fassbender! Is that a snake in your pants or is the Fassdong just happy to see me? Oh yeah.
