The clue to this is the "(/v/)" next to the disability social autist (the joke is people who go to /v/ are social outcasts/have autism) manly tears is a specific poster on the imageboard who went out of his way to troll people (by assuming a name so he wasn't anonymous anymore and just being a dick). He posted one picture too many and people pointed out he looked short, then whenever he posted everyone turned up with short jokes, once he stopped getting the reaction he wanted he stopped turning up.
It's just an injoke, that was why I said I was surprised it had turned up here.
