A party where all the guys are there just to jerk off, and no one cares if they do it alone or in a big circle jerk. Sometimes they play soggy biscuit for fun.
Bro, this jack party is just a bunch of guys jerking off in the basement.
I came to this jack party just to see if they do the circle jerk again.
My friend said the jack party is the best part of the weekend.
