look up any word, like thot:

"Dude we're up 6 to 5 going into the top of the ninth. I can't believe how hard I'm Jenking Off right now".

Jenking off is the act of taking a big whiff of jenkum before jacking off, using the left over sewage from the jenkum bottle as lubricant.
I heard Steve jenking off in the bathroom at school.
