Jack Threads

An advertiser on Urban Dictionary that promotes ridiculous Nigger costumes as "mens wear". Also any clothing worn while jacking off.

I wouldn't even wear Jack Threads to masturbate. I prefer a wife beater and boxer shorts.

Jack Faced

It's the look you get when one of your parents walk on you jacking off. You usually stare at them with an open mouth saying "uh," and it's followed by "It's not what it looks like," or "I was just scratching."

"Man I was totally Jack Faced when my mom walked in on me jacking it."
