jiggly flapjacks

The degeneration of masculine pectoral muscles and turning into fatty, especially flabby tissue.

Dude used to work out all the time. Now his pecs are just jiggly flapjacks. I can’t help but imagine them flipping when smacking them from the bottom up. Lol.

When you’re having sex with a partner and you RKO them mid orgasm.

Flapjack

Corporate cocktwaddle used by lower middle management in a passive aggressive manner, trying to convey an image of bringing ideas together - generally talking shite using words they don’t understand but have overheard whilst thrapping one out in the bogs.

Lets flapjack the shit out of that idea!!! If you don’t lay an egg on it by close of play your cock is on the block!!!

Flapjack

The female version of sending a dick pic

"Send me a Flapjack"
"You what?"
"Let me see you Flaps so I can Jack off"

Cincinnati Flapjack

you take your girl and 69, then stick your cock so far in she throws up from gagging. Then get a condom and fill it with the throwup and store it in a freezer. Then eat it like it is a popsicle

Bob said," The Cincinnati Flapjack" is such a fun thing to do on Valentines day
