Kris; "And he has no idea you were bouncing on another guy last night?"
Frannie; "Nope. He is such a Jare."
More specifically, this is the alternative to a dare in the game Truth or Dare. If one takes the dare and decides after having heard the dare that they don't want to do it, that person must then accept the Jare.
Also referred to as "Dick Kick" or "Poon Punch."
