A faggot and or retard that you happen to notice while in the presence of adults.
Obviously upon hearing you say retard or fag they become all pissed off. So. You simply mutter it to yourself. And more or less the adult will leave you alone.
Kid: Freakin' Retard!
Adult: KID!?! Watch your language!!
-Mubles: Freakin' Tart.
Adult: Hmm. What?
