Sack Knuckle 

When a man is wearing tight pants and the crotch seperates his testicles showing a bulge on each side of the seam.

Look at that guy, his pants are so tight I can see his sack Knuckle.

Five course knuckle shuffle 

A meal eaten in a Mayfair Wankpit. There are usually at least five courses, none of which satisfy, and all of which cost far too much. The expression is derived from one of the traditional euphemisms for masturbation: five knuckle shuffle. The obvious implication is that the five course meal really is a pile of 'wank'.

Gwendoline, this five course knuckle shuffle is taking the edge off my apetite for the supper we will have in that other Mayfair Wankpit. I may well have to leave it on the table.

Sticky Moose Knuckle 

When a man originally born and raised in Canada balls his hand into a fist, pours a reasonable amount of Aunt Jemima's Maple Syrup onto his knuckles, and shoves them inside of a woman's vagina.

"I met this keener of a broad last night at the pub and gave her the ol' Sticky Moose Knuckle eh?
