When you make a truthful statement, that is so brutally honest its as if you slapped the person in the face with the truth.
Dude: Guy, you're so ugly you couldn't get hit on at a convention for the blind.
Guy: Ouch, that's harsh.
Bro: Slap Truth!
Guy: Ouch, that's harsh.
Bro: Slap Truth!

Get the Will Smith Slapmug. A craze where complete idiots in an attempt to gain popularity with their complete idiot friends film themselves attacking innocent passers by.
this happened to me once , there was 2 boys about my age and one had a video phone pointed at me and the other was walking over to me , the boy went to happy slap me and I headbutted the tosser right in the nose and chased his friend off. Though if it happens to you and theres more people , just run.
