1. An incredibly terrible clan called the International Society of Maniacal Killerz that once existed and flopped within days after achieving about three members.

2. Any clan that seems to have no purpose or is very bad at any game.

That clan is so ismk, they've lost every match!

1. A horribly designed website, made for the outdated clan ismk, but now it simply exists for no purpose.

2. Sometimes used by the few people that visit ismk.net to insult other things.
