When during the act of sex, one person is observed making a bizarre facial expression or expressions that make them appear to be mentally incapacitated, or at best, just looks silly.
Guy #1: So you hooked up with that girl last week? How is she in the sack?
Guy #2: Everything was good until she suddenly had this totally weird look on her face that stopped me cold/made me laugh
Guy #1: So she's got Retard O-Face?
Guy #2: Yep.
