cmf 

A cool music fan. Defined as one who goes to concerts all the time, whereupon he or she looks cool and dances stupid. Interesting as the word "cool" modifies "fan," while it is not obliged to modify "music."

Possible reaction upon meeting a cmf:

Omg, a concert a night? You are a total cmf. I love you forever.
