The Unicode null character, , which often terminates a null-terminated string. Its mere presence in a string (outside the end) will always cause software bugs. I tried to include the character itself (faulty PDF OCR from an underlined “가”, confirmed through a Unicode converter), but it would always cause UD to error (obviously).

I used empty brackets because I tried to insert the actual character, but Urban Dictionary would always

. Blank, that is it .

" " (U+3164) is a blank filler code that is invisible, and can be used in places the space key can't. most places where you can name yourself you can't use just spaces, so this works for an invisible name or almost any other reason. if you are not able to use it in a place, put periods or another symbol on each side of the ' ' and it will usually work.

murderhobo

In a tabletop game, a murderhobo is a player who murders NPCs indiscriminately. This is normally derogatory, referring to a player who totally ignores quests, dialog, backstory, trade, world building etc.

The term is most common with Dungeons and Dragons, but it can be applied to most RPGs where the player is allowed to kill most quest-giving NPCs and NPC traders. E.g. Elder Scrolls, Fallout, Divinity original sin.

DM: The sad little orphan girl tugs at Steve's trenchcoat to get his attention, and ask for help saving her pet dog from...
Steve: I'd like to roll a strength check against strangling the orphan.
Dave: I call dibs on the dog.
DM: You murderhobos disgust me.

Whale

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.

"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."
