This is how I see them.
thisismyusername: sassy and intelligent, gay and opinionated, faces accusations of being "racist" but BBC isn't for everyone, seems proficient in coding and all that mainframe computer shit.
StealthFan: another bro rekt by mental illness, once a slick willy in the pussy game but now prediabetic from his prescribed atypical antipsychotics, shamed for saying questionable things but chalk it up to his beautiful mind.
That said, he will rise again, stabilize, lose the weight, reenter the workforce, and still get laid more than Atra. No more Wii U's, no more NEET bux. Instead, his reemergence will usher in a new era of dank memes.
King of the Internet: self-deprecating yet unabashed, depressed and self-medicating, fingerbangs mad chicks while lookin like Bale in the Machinist, at peace with his degeneracy, though I'm not convinced he's actually a bad person or as bad as he portrays himself to be.
TL;DR (AiA edit): Just a bunch of cacs.
