What does brick squad mean?

Brick Squad was originally a record label founded by Waka Flocka Flame, a hip-hop artist from Georgia. In recent years, however, the definition of “brick squad” has evolved in slang to be about anything or anyone cool, tough, or awesome

Examples:

• Cool: That new album your fav rapper released the other day was the absolute brick squad.

• Tough: You’re definitely brick squad for sticking your hand in your dog’s mouth even though it’s drooling from how excited it is to see you.
