Jump roundhouse, crouching medium kick, hadouken... thats a scrubby combo. Oh wait, fps... Hmm... dont care enough about the genre to list. But a "Noob combo" is something that is effective with very little effort seems to be something I should try to do. Only using pistols because it takes more effort or something like it is fuzzy logic. Its like picking Ryu from street fighter and not using hadouken because its very useful and it helps you win a lot of matches. So it takes more work, and needless effort to play without it. But it is very very stupid to not use it (the "no hadou shoto" as its known). But since most are talking about COD4, I'd say almost anything can get you kills with no effort, so basically everything in the game is a noob combo.
