The facial expression you get when you're faced with an awkward silence cause by an ignorant comment that everyone seems to have ignored. Numma can also be frustration, anger, or confusion because of any given situation. Numma can occur after a racial slur, a demeaning act of hate or when that asshole next to you decides to steal your chicken.

Side effects of Numma may include:
headache, depression, facial irritation, itchy balls, or a simple brain fart.
