What is Y'ince!?
1.
1. A high pitched sound made when the Y'incer removes his hand sliding it across his hair after tricking the Y'incie into a fake high five, this is normally done by the mentally handicapped as a form of amusement usually resulting in akward moments of silence.
2. Sometimes used as a substitution for everyday verbs (see examples)
Guy1: hey man high five *holds out his hand*
Guy2: *goes to high five guy1*
Guy1: *Pulls hand away and slides it across his hair* Y'INCE!!
