If you are actively trying to trigger people then I don't think you'll have much success here. Also, I don't really think it's appreciated.
ok. i got this. forums - orums = f. F like fandom. terraria = A Alike Anime. jesus that some deep things.......
or maybe these people with avatars are like dirt in terraria? you see it a lot. but there is more of other items.
I'd guess most avatars are either related to terraria or those default avatars when the person didn't choose a custom avatar.
