knuckle bump

To snort a small amount of cocaine from the creases of your knuckle. Usually the most discreet way to snort in public (club, party, street) so that no one will suspect anything.

Ben: Did you see that chick knuckle bump?

Tice: I sure did.

Knuckle Sludge

Extending one's finger and ramming said digit into the anus until the knuckle reaches the rectum.

Nothing beats reruns of "Welcome Back Kotter" and gettin' the ole' Knuckle Sludge.

Ugandan Knuckles

A early meme of 2018, of a weird model of Knuckles in the popular VR game VRChat asking other people of they know the way. This meme quickly spread fast and with that the meme died. Many people still use the meme today despite it's zombie-like status as a dead meme.

Person: I love Ugandan Knuckles!
Other person: I think it's meh.

When smash a girl's giner with your knuckles and they shatter like butter you get a knuckle hucker.

Fuck knuckles

Fuck knuckles are when a teenage boy has been masterbating and constantly has jizz on his knuckles

I will never shake hands with my nephew Johnny because he constantly has fuck knuckles and seems to be always jacking off.

Trust Knuckles

The act of two persons touching fists with their knuckles lined up to indicate agreement or as an encouragement. An alternate of the high five.

So we'll meet at 3 at the restaurant, trust knuckles, later.
Way to get that job, trust knuckles.
