When you first squeeze the ass there is some give, giving the squeezor the illusion of a "Fat-ass." However, upon further squeezing, the squeezor realizes that said ass is rather lean at its core, hence the name hackey sack-ass, due to its resemblance to a hackey sack.
Girl 1: "Ya I thought his ass was fat but upon further squeezing I found it to be rather firm."
Girl 2: "Like a hackey sack?
Girl 1: "Ya Totally, it's a hackey sack-ass!!"
Girl 2: "Like a hackey sack?

Similar to a ball sack just hanging from your ass. May come from surgery or minor misfunction while growing in your moms vagina. Very droopy and hairy. Hurts when kicked. Very pleasurable while licked.
