M$

Typically used as a derogatory term for Microsoft. Typically used by those who use Linux as their operating system, it implies that Microsoft, a business, cares about business-related things.

The person said M$, so I naturally dismissed their opinion on what is the best operating system.

M

the ESRB rating that stands for Mature, 17+. It basically means it has lots of violence or sex and stuff, and that stores are supposed to check id's when selling the game (unfortunatley, they actually do)

darn that m rating!!! It means I can't sneak out and buy Grand Theft Auto San Andreas at Best Buy. I guess I can try downloading it...
