"Mah" is one the most versatile words in the english language. It can express almost anything as long as it is pronounced, emphasized, and coreographed correctly.
Mah is a celebration by two or more bros that typically involves drinking, Mario Kart, and life talks.
It is best celebrated in a starlit field or other outdoor location, although one's basement may be used as a substitute during the winter months.
As made apparent by the name, MAH must be celebrated past midnight.
