Knuckling

Knuckling is the act of 2 bros fist bumping eachother. As the two bros fist bump eachother, a third bro proceeds to slide his dick between the other bros touching knuckles. He then proceeds to fuck their knuckles.

White-knuckling the basket

The disregarded worry stemming from sleeping with a promiscuous woman who hasn't been tested.

I knew she'd been with a lot of men, but I couldn't resist. I was white-knuckling the basket through the entire session.
