Silly Cadey Fact: Back when I played Maple Story, "Cash Item" was actually censored, you could not type a message containing that phrase, so I started calling them "Cash Shop Items" as a result.

The reason "Cash Item" is censored? Because it contains the word "shit" but with a space in it.

Thinking about it, I also sometimes called the "cash 'items" as well, because an apostrophe worked for blocking the swear filter.
@cadeybunny Hahaha! That's like stuff that won't let you put your home town if you live in Scunthorpe.
@RetroSponge Did you know you used to be unable to trade a Cofagrigus on the GTS in Pokemon, without giving it a nickname? Because it contains the word "fag".
