The Sonic & Knuckles Effect only happens when 2 characters are compared to each other. One character may have more careless, goofy, "radical" behavior, and the other character may have serious and focused behavior. The original form of the Sonic & Knuckles Effect was, well, Sonic & Knuckles, with Sonic being the more careless character, and Knuckles being the more serious character.
Person 1: Hey! Cmon, what are you doing here just sitting around?
Person 2: I'm trying to look after my belongings.
Person 3: It looks like you two have the Sonic & Knuckles Effect

A crusty knuckle is when you have your girl stimulate your prostate by shoving her middle finger up your anus. Look at her knuckle once she is done.

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.
