I find it funny when I am playing a game, something goes wrong, and I lose in a spectacular fashion. For example, attempting a tower rush on oasis, getting beaten back, and having a slung Aztec with eagles wipe me off the face of the map. My allies call me a noob with all sorts of adjectives.
Then, with that in mind, I try to go into a game marked "noobs only." And they kick me out.
Noob definition: Trush on oasis.
It was wide open, I was close, and I was able to do a 19 villager build up. He didn't wall off, he was just able to play defense.
Not all oasis maps are the same. Flanks can drush, flush, or do all sorts of crazy stuff. Trushing isn't necessarily noobish in and of itself.
