The XKCD substitutions browser add-on, of course. Do you remember what you said when I shared it with the forum?
taw if you change the names of forumgoers i swear to god
What have you got me as?
Nothing at the moment. I have Arcvasti as "Kōhai"*, Footkerchief as "Search Engine", FearfulJesuit as "FootJob", Tiruin as "Eirika", and the other day I took the "That" out of "That Wanker" because it was cluttering up my text formatting (I got both words to be capitalized by putting eleven spaces between "That" and "Wanker"; in normal text only the first one appears, but when I open a text editor, like a posting box, I have to manually remove ten spaces.) I consider new names often, though.
It used to be much worse, I originally replaced everything I could think of with it, which made normal text almost unreadable.** I had to keep it off unless I wanted a laugh.
* He has me as "Senpai" because I introduced him to the add-on.
** A small list:
"Comic Sans" became "unholy fuckfire"
"Democrat" became "Goff", "Republican" became "Prep"
Toady was "Sanic Hegehog" and ThreeToe was "GottaGoFast".
The utilities bar under the DF updates on the forum was given a gangster makeover (e.g. "home" became "yo' pad")
"Slaves to Armok: God of Blood: Chapter II: Dwarf Fortress: Histories of Greed and Determination" was replaced with something utterly ridiculous I don't even remember.
