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!!".
