Slap upside the face
The polar opposite of getting slapped upside the head. A person will take their hand like the are about to slap someone but push the person's chin up an smush their hand in their face. New fad that originated January 7th 2012 created by two siblings in Walmart

Because of the way the face is pushed when this occurs it results in the embarrassment of the person slapped an a moment of silence
Toni: shut up derek before I slap you upside the face

Derek: okay okay dude I will stop

Tina: I shall slap upside the face of yours for being a turd

Gina : sorry please don't do that
