jack jelly
When a man uses jelly or jam to rub his privates while he wanks because he’s either broke, lazy, or has a weird snack fetish.
He used jam to jerk off because he ran out of lube and had a PB&J sandwich in his hand.
My brother used jelly to wank because he thought it was a snack and a lube combined.
I used jelly to jerk off because I had a food coma and my brain was too slow to open the lube.
