Jack Coff

A crank name, similar to Ben Dover and Pat McGroin. Sounds like "Jack-off" if said correctly.

Heya. Ben Dover, Pat McGroin and Jack Coff.

Going Jack

someone who slowly begins to lose their mind due to utter boredom, isolation, a creative block, cabin fever or all of the above, like the dude Jack Torrance in The Shining.

I hope this snow storm lets up or I am gonna be "Going Jack" soon.

jack off

if you're under 13: you're not cool enough to know what it means. come back when you wake up and its sticky in your danger zone.

if you're over 13: why the FUCK would you need to look up the definition of "jack off?" did your balls not drop yet?

why the hell would any guy who's hit puberty need to look up what "jack off" means?
