Dap Snake 

One who thwarts your attempt at a traditional hand shake by manipulating your hand into the more Urban "Giving Daps" in which you are forced to grab fingers until the stress point is reached - once hand break free you are obligated to snap your fingers. (Other variations of "Giving Daps" are common)

That Dap Snake just molested my hand to no end.
