Andy couldn't decide what drink to get, so he went with the all-encompasing angry black man.

Angry Black Man
This is a term used in sports, and most commonly in basketball. It is when a black player on one team gets real pissed, and goes into Angry Black Man mode or ABM. The player then becomes unstopable, and only stops once he is no longer angry.
Signs of ABM are when a player dunks and looks pissed, or makes a jumpshot and looks pissed instead of happy.
