a word to describe what you’re feeling; skrunkly, silly, a little bit sickly, and (most of all) rhetorically funny.

“bro I can’t believe I suck so much at this game”
“hey man it’s fine you’re just feeling a bit gundueous”
——————
*tells bad but funny joke*
“man what’s up with you today, you’re so gundueous”
“thanks?”

newton's grundle

A phenomena occurring during gay sex where the giving man's scrotum slaps the receiving man's scrotum, sending them forward to the grundle then back to hitting the giver's scrotum, which then swing backwards, and repeats.

This is derived from the desktop toy known as Newton's balls

Hannable was riding Adam so hard that the Newton's Grundle could be heard from outside the bathroom.
