(backtick-two) An Urban Dictionary editor's best friend. Clicking these while in edit mode will cycle through each definition and mark in "reject" for each entry. This way, you don't have to actually try to read the (mostly incomprehensible) definitions while you edit.
Don't feel bad, 99% all the new definition entries are utter shit so there's nothing to lose.
I think I will go into editing mode on Urban Dictionary and `2 my way through several hundred new definitions that are all worthless trash written by 5th graders.
Called such since /2 is the command to bring up trade chat (by default) from the chat line.
2. Trade Troll1: Dude, where's my murloc??
2. Trade Troll2: Lord of the Murloc
2. Trade Troll3: Harry Potter and the Murloc of Fire
2. Trade Ghostcrawler: Oh god. Not this again. GTFO MY /2!
