Dipsy-Doo
While playing any online FPS, a Dipsy-Doo is the use of tom-foolery in order to trick a chasing foe and killing him/her. Doubling back directly after entering a door, and going up stairs, jumping down and returning to the same stairs are consistent to be the primary techniques used but are not the summation of all pro's of the pwn.
Oh fuck brosif I just Dipsy-Doo'd this nub who chased me up a ladder. I jumped back and while in mid air knifed his dome-piece.
