Jacket and Jack It

The motion of getting your jacket, placing it over your crotch area, sliding your arms under the fabric, reaching for your dick with a hand, and masturbating away. The move is usually used for concealment when in a public area while having a very high sex drive.

Isaiah: Yo bro, I got nudes from her yesterday while I was in Walmart and I just had to jack off then and there using the jacket and jack it method

Brandon: Really bro? I got caught and kicked out of Target for doing that

Brian: I don't use the jacket and jack-it method. I just take my dick out in public and jerk off in front of everyone
