This prank occurs on April Fool's day. It involves attempting to play a prank on someone, backing down and telling them that you are joking, and then doing the prank anyways. In essence, one commits two pranks in one swift motion, simliar to a boomarang or maybe a pulley of some sort.
You go up to someone, for instance, on a balconey or some higherlevel building, and say "I'm going to push you off the balconey," then, "Hahah, just kidding, April Fool's" but you push them off the balconey anyways.
