Initially an internet version of the Wojack guy, a Coomer is a male chronic masturbator, an Incel on steroids, who lives in front of his PC consuming porn all day, and having no other interest in life other that to reach his next orgasm.
Coomer now refers to any young man who is solely concentrated on an almost psychopathic need to chase the next dopamine hit, be it masturbation, game score, high of any kind. Coomers are now utterly useless self-pleasuring addicts, to the exclusion of any future career development or frankly any future plans at all beyond the strict need feed their addictions.
Haven't seen Geoff in ages? Yeah, since he lost his job and his girlfriend, he's locked himself in his room with packs of beer, a pack of toilet roll and Pizza on speed dial. Even skipped his mother's funeral. Total coomer now. Sad.
A phrase used by many people as means of justification for an older person doing or saying something typically racist, sexist, or simply insensitive. This is said because these senile people come from a time when Jews were thought of as lesser, being gay was automatic hell in your life, and don't even get me started on being black.
Gramps: Those damn Jews and their smartass Asians are stealing all of America's money! I bet they're gay too!
Donny: Sir, I find that highly offensive and racist. Bro, can you please control your blatantly racist father?
Butch: I'm very sorry bro. But you know, he comes from a different time.
Donny: I guess it's ok then...
