a shitty band that everyone hates
brain pollution sucks
A person who talks about the same thing in same way/or rephrased way, for two or more times without any reason, even when the audience has completely understood the point he/she is making.
That dude mass brain pollution because he keeps repeating himself. He was saying, "So we all went to this great place, then we went there and after we went there, actually we went there and something happened before we went there, so let me fort tell you what happened when we went there."
