Sporkmouth 

Sporkmouth. Being born with a white plastic spork in your mouth, the opposite of being born with a silver spoon in your mouth

Guy 1: I say Tarquin, take that silver spoon out of your mouth for a minute and look at those ruffians over there.

Guy 2: Gosh Wills, sporkmouths! Let's get out of here before they see us.

Guy 1: Yes, make haste!
