The character of Carmen was never really explored in either of the game shows. In the animated series (which used to be avaliable to watch at Yahooligans! c. mid-late 2005), her history was fleshed out. She's best known for wearing a red trench coat, a matching fedora with a yellow band (which also conceals either her left or right eye depending on what piece of art you're looking at), and high heeled shoes.
Since Carmen Sandiego stole anything she could (statues, landmarks, rockets from Nasa), her name has become an almost stand by. If you wanted to make a joke, you would blame her for something you've had stolen or misplaced.
Guy 2: Damn you Carmen Sandiego!
Said in frustration to lighten an aggrivating situation when someone is lost and doesn't want to stop for directions or can not find there party member at a large gathering such as a theme park, convention, or festival.
"I've had it with your mind games Carmen!"
Something said from a guy who is frustrated with a girlfriend or girl he is interested in who is being coquettish, flirting, or giving mixed messages. Generally the girl is considered cunning or minipulative as well, referring to Carmen Sandiego's affinity for cat and mouse style games.
"Where in the world is my Candy?"
A pop-culture reference to a Strongbad Halloween cartoon where Strongbad cross dresses as Carmen Sandiego and goes door to door using the Carmen Sandeigo slogan. This slang is generally only used by annoying kids who go door to door for trick or treats who want to say something other then "trick or treat" and are obsessive fans of the e-show.
"Fuck you and your VILE League Carmen"
Anything referring to "your VILE league... Carmen" is a new slang insinuating that a person (female generally) isn't fighting fair. They have either cheated, stacked the deck, or have a large number of people backing them up in an arguement/debate that was planned in advance without the oppenants knowledge ahead of time. This term is meant to be deresive but humurous, it often means that the person being called "Carmen" is cowardly and has to have other friends to back them up in order to win an arguement and puts alot of time and effort into conspiring against others.
"I found you Carmen"
Term used when one person spots another online that is lurking in a chatroom or message board that has been gone for a certain amount of time without notice, and quite suddenly reappears for whatever reason.
"VILE Strikes again!"
An explanation being used by "smart kids" or "retro" fans anytime something odd or unusual is stolen in news or media or a new conspiracy theory is introduced or crime has taken place where an explanation can not be given as to how the criminal act was achieved. Also included is paranormal activity at historical land marks, more then likely generated from an episode of "Where on Earth is Carmen Sandiego" where V.I.L.E. manages to fool authorities into thinking Carmen Sandiego is the ghost of Mary Read.
