When your masturbating and you flip your dick over and under in your hands , just like flipping a pancake.

When your're wiping your ass, and you check the paper to see if you're clean. It's look clean but a flap of the toilet paper folded over the poop. So you get up and go about your day thinking you're clean. Then you get home and see that your underwear is ruined. You got jacked by the flap. You got flapjacked.
*taking off clothes after a long day* *sees stain in underwear* Oh man! I must have gotten flapjacked.

The striking of the upper, inner thigh region with an open palm. Striking as close to the genitalia as possible without making contact.
Corey was being a real pain in the ass, so when he was sitting down I flapjacked his stupid ass. Now that asshole has my handprint on his thigh.
