saba knuckle

when a dudes' slacks are so tight they squeeze his twig and berries into a rhino beetle head shape to make them protrude like a ball-dick boner from said slacks; you know, grab a bowling ball with the correct grip (hand palm up, pointer and middle finger curved up and middle finger curved down, ring finger and pinky tucking into palm. pointer and middle finger would be balls shooting forward and up and thumb would be chub chub jutting forward and down.) now you see it, bro? ;)

Dude, i love Led Zeppelins music, but can't stand seeing old video footage of them. Every time they have wicked saba knuckle.

Knuckle Theory

A theory used by measuring the number of days in a month. If your index finger touches your knuckle of your hands, the month has 31 days, while if you touch the skin of your fist, it has 30 (with the exception of February).

Scott: Dude, how many days are there in August?

Dave: 31.

Scott: Isn't it 30?

Dave: Use the Knuckle Theory.
