Put it on Knucks

"Put it on Knucks" is a type of fist bump done by two friends. When this fist bump occurs, or is brought up to be done it lets the two friends know they're telling the truth, being serious, and that they're confiding in one another.

You: Dude, I just hooked up with Ms. White

Me: You're such a liar.. yea right.

You: I'm being honest but you can't tell anyone I told you.

Me: Put it on Knucks

You: Fine.

*Fist bumps each other*

Me: Omg, you're so lucky.. did you get pics?

Knocking

Modern cars are prone to low-speed knocking
