I work with a guy like this. Lead his icebreaker with "I don't understand people so don't expect me to interact with you."

He's the most brilliant person I've ever worked with. His knowledge is encyclopedic. He will show you how what you're asking is idiotic in as few words as is necessary. He has no fear of manager or customer.

He has my eternal allegiance.

First line reminds me of office space

I don't tknow the coworker, but OP is obviously GAY.

They are both autistic.

Autism/Chad horseshoe theory

I've been in this literal exact situation. If it hadn't happened 20 years ago I'd be worried this anon is talking about me

Gigachads don’t shout, do they?

Fake: woman interested in man

Gay: anon is jealous

Sounds like a man who knows what he likes and doesn't want social involvement with people he doesn't like. Why does that behavior have to have a name?

Is this situation plausible?

he's GAY.

HE'S LITERALLY GAY

Could simply not be interested?

As opposed to inaudibly shouting

An autistic gigachad, obviously.

Possibly his support worker? Maybe new one hasn't been hired yet!

He's Neo from The Matrix, dodging bullets.
