A person who replies in a forum, when their point had already been refuted in
the first, or previous posts. This

the person did not read, and responded blindly making themselves look like an idiot.
Hence the "TL:DR" in the name.
Person 1: *long, thought out,
intelligent forum post*
Person 2: That is a bad idea, because of ____
Person 1: I already
explained why that
doesn't matter. Ugh, i bet you didn't even make it past the first paragraph you TL:DRetard
