Cool bro, 

When some one tries to be cool by telling you something, but you don't give damn, that's what you say.

Looser kid: hey! I just prestiged in call of duty!
You: cool bro,

Random friend: you have no friends.

Not Cool Bro!! 

The phrase of choice of a very loud Armenian male population, especially from Glendale, CA when they disapprove of anything not to thier satisfaction. Normally said in a very loud, booming voice with a rolling 'rrr'. This phrase is used mostly in driving situations where the all too perfect Armenian driving style has been disrupted in some way.

Shouting from his driver' side window - "Hey BRO! Not Cool Bro! Why you make lane change my lane when you KNOW I coming BRO!?? NOT COOL BRO!!".

What you sarcastically tell someone when they're saying something cool yet uninteresting. Abbreviation= TCB.

Cody was telling Susie a story and instead of telling him to keep going on she said that's cool bro instead of cool story bro.
