BOY THAT'S CAP! 

Is something you say when you don't want to get caught in a lie, but instead of coming up with a reason to support your lie, you just keep saying "BOY THAT'S CAP!" and get louder with each one, until eventually they just find out that you're full of shit.

Bruce: "DeAndre literally copied my Essay word for word, he even used the same font."

Painter's Cap

House painter's lingo for smoking marijuana before or after actually painting. Much better before yet not so bad after.

Putting on a painter's cap = Getting high!

Painter: Hey Dude, let's put on a painter's cap before we tackle that living room.

Painter 2: You got any?

Painter: You know it dude. Straight fire!

Painter 2: Awesome! Let's do it quick before the boss show's up!

Painter: No worries man! Who do you think I got it from?

Painter 2: Nice!

Chewing the clown's cap 

Getting less than you bargained for.

The date with the good-looking blonde was a disaster. She turned out to be crazy and Bob realized he'd been chewing the clown's cap.

slummer's cap

A flat cap (usually a working-class article of clothing) when worn by someone well-off.

My usual outfit for a black-tie dinner is a suit and tie with a slummer's cap for a little flair.
