Breakdancing Coin 

When a person drops a coin and a rhythmic circular movement ensues, causing the coin to breakdance so fast, that it can only be stopped by standing on it.

(man drops coin):

Man 1 : ohhh man look at that coin go!

Man 2 : yeah fam, that coin is breakdancing!

Man 1 : Yeah, that is one sick Breakdancing Coin

Money. Safe bet. Expensive. Pricey (but worth it).

That (expensive, high-quality item/thing you want) is serious coin.

-Candice is outta my league, man.

-I know, dude. She is sooo money.

-Right? Serious coin.

Rusty coin purse 

When you bang a chick while she's on her period and your balls get all "rusty". Not to be confused with red wings which is when you eat a girl out on her period.

I fucked this ho last night and I didn't know she was on the rag til the next morning when I saw my rusty coin purse.

Challenge Coin 

A Challenge Coin is a quarter-size bronze disc that one cadet can give to another cadet. If a cadet gets one, he must do whatever the other cadet challenges him to do.

Matt gave me a fucking Challenge Coin -- I have to give a blowjob to any other cadet in my graduating class who wants one, but I have to ASK if they want me to suck their dick!

Challenge Coin Tasks

Challenge Coin Tasks are the things you have to do to fulfill your obligation to the cadet who gave you the Coin. Mine was to ask each cadet in my graduating class if I could suck their dick and swallow their load while I jacked off and blew my load.

When I go to the cadet showers every morning, I look for guy's who haven't taken care of their morning wood and are walking around with raging boners. Then I fall to my knees in front of their hard-on -- they usually say "go for it!" - I do and complete one of my Challenge Coin Tasks!

jungle bridge coin 

Jungle bridge coin is an imaginary virtual currency that can be referenced as a sarcastic rebuttal to your peers relentless efforts to convince you to invest in Dogecoin.

I haven't invested into Dogecoin but I have invested my entire life savings into Jungle Bridge Coin.
