Slick Stacking 

Group slick legging, where each man is positioned on top of the other like a stack of buttery pancakes (except they are mancakes).

A slick stack of 5 or more can also be referred to as a slick tower.

Back in my day, slick legging was between an inmate and his cellmate. Kids these days do not have any respect for traditional slick legging, now they won't do anything other than slick stacking. What's next? Slick squirreling?

The other day me and my friend were playing Streetfighter and I beat him with the move A Side Slick Swirl Kick!
