A n00b and/or nub who constantly gets pwned in xbox/ps2/or life. Goes very well with a nub and/or n00b cake. Following with a glass of nub milk will ensure pure pwnage. Anyone considered a noob muffin sucks entirely and should never game/live again.

Another way of saying "Noob" but with the word muffin to add some spice to the insult. No-one wants to be a muffin and a noob at the same time either.
Hey look at that noobmuffin he fucking died before the round started.
