look up any word, like fleek:
 
1.
(n.) A seemingly complimentary statement, usually said by one female to another, that is covertly derogatory or insulting in nature or intent — perceivable only to the individual to whom the statement was directed and nobody else.
1) Example of an archetypal "hidden brick" between two females:

Alexandra: What do you think of my engagement ring?
Becky: It's cute.
Alexandra: What do you mean it's "cute"?! This ring is BEAUTIFUL, you bitch!

2) Male counterexample:

Andrew: What do you think of my new crossbow?
Ben: It's cute.
Andrew: Screw you! This crossbow is friggin' BADASS, you dipshit!
