WHATS A RAP TRISTE

So the beat of today is RAP TRISTE I really don’t know what that is, Is it when I’m becoming combative On when I’m on the stage in action, Is it when I’m the major attraction And I’m entertaining the masses When I’m rocking the crowd with passion Or showing my style thats new in fashion Is it when the MCs just start clashing, when I get on the mic an smash’em When my timing is off by a fraction I’m not getting no satisfaction Not recognizing who and where put the trash in Would someone please tell me whats a RAP TRISTE???
