I picked "Cameo" out of a name book, but it was too short or too generic for most websites, so I made puns on it because I hate putting numbers or special characters at the end of my username to distinguish it, and CameoAppearance was the one that stuck the hardest.

takethatnature (Wilson) is an in-game quote that I figured was both characteristic of him and distinctive enough that I wouldn't be competing with characters from some other fandom. It's his quote for the cut-down stump of a tree.

configuration_birdwatcher (Bastion) evolved from "configuration_disneyprincess", which came to me in a prophetic vision on a long walk home after missing the last bus late one night in the summer of 2017 but turned out to be too long. Just as well, because configuration_birdwatcher is much better anyhow.

It's about (pinchy hand gesture) the contrast between technical nomenclature borrowed from their canonical alt-forms and a nature-oriented hobby

death_fangirl (Aradia) is a canon quote; Terezi describes her as having a D34TH F4NG1RL TH1NG right after everyone meets up by the Green Sun, and I play her nigh-exclusively from a post-godtier canon point, so it paints an accurate picture of Aliveradia's personality.

causeofthethingwiththehat (Yochelm, a Glitch OC) is the absolute shortest version of what his name means in Ninuanni that I was able to fit into the character limit.

moisturewave_aesthetic (Cirava) is a bullet point from their original Troll Call card, minus the decorative special characters. They like Alien Vaporwave. I had to put an underscore in it because there was another Cirava using the version without one.

two_souls_wedged_inside (Webber) is a really obscure canon quote. The Webber's Skull item doesn't appear in Don't Starve Together, but most of the DST-exclusive characters have unimplemented quotes for it hidden in their files. Local soul-eating demon-thing Wortox's quote is "Hm. There's two souls wedged inside."

Which I thought was going to be too long, but it fit!

(I really didn't want to take any of the underscores out.)

moisturized_inmylane (Walani) - not to be confused with Cirava's similarly moist username - is the short version of a meme that suits her, as a chill surfer girl.

impostor_syndrome ("Purple", an Among Us OC) is a pun that I couldn't believe nobody else had made yet.

fullofemptiness (Wendy) is another canon quote; when her hunger meter gets low she says "I am full of emptiness."

lonesome_moonflower (Wormwood) is a combination of his canonical title, The Lonesome, with the broad name for night-blooming flowers. Which are relevant partly because in his cinematic he started blooming at night on the first day he was alive as himself, but mostly because his gem came from the moon.
