A depression jack is when you take a zoloft on an empty stomach, wait around 25 minutes, and start jacking off. You win if you finish before you go limp-dick.
I tried a depression jack for the first time yesterday, but I waited too long, and my dick turned into a noodle
Dirty jack young is when you fist your sister while wanking in a Spanish classroom then after you finish you spread your cheeks and force your sister to give u a rim job
