H.M.C. Stands for "Heavy Metal Club". It's a group/club with members who wear colors just like a motorcycle club, and have by-laws and a hierarchy. Most are local while the bigger, more recognized ones are international and have chapters throughout the world.
Dude, the local H.M.C. were all at the show last night in full regalia.
