To do something to a fictional character with significant popularity to make said character unpopular. This is most often done out of trying too hard to promote the character so that it backfires. However, it can also be done if other characters are desired by their creators to be more popular than a given character created by said persons.
Taken from the Street Fighter character of the same name, who has gone through being upstaged by a character with the same fighting style in the Alpha Series, not being updated nearly as much as the other characters in the series as time went on, as well as the indignity of being portrayed as Jean-Claude van Damme in the worst game-based movie of all time.
I used to like Daredevil in the comics but the movie about him really guiled him for me.
Nothing can ever guile the Looney Tunes, not even Space Jam.
What the above person said...plus he does Sonic Boom and Flash Kick
He is a character from Street Fighter series. His real name is William F. Guile. Guile is a colonel is the United States army. He uses a combination street and military fighting style, and sports a unique flat-top hair cut. He has sworn revenge against M. Bison, the ruthless dictator who killed his best friend Charlie, years ago. He occasionally collaborates with detective Chun-Li to share information on and combat M. Bison's Shadowloo terrorist organization.
A character in Street Fighter, a series of video games by Capcom. In the games, Guile is a major in the US Air Force. According to Street Fighter II, he was born on 12/23/1960, he's 6'1" tall, weighs 191 lbs, has type-O blood, and his three-size is 49-32-35. Guile's most famous moves are Sonicboom and the Flash Kick (AKA Somersault Kick), and both were taught to him by Charlie, Guile's superior officer and friend in the US Air Force. In Street Fighter II (his 1st appearance)he abandons his wife & daughter to get revenge on M.Bison (Vega in the Japanese version) for killing Charlie in the Street Fighter Alpha series. In Street Fighter IV, Guile abandons his wife for a second time to search for Charlie, of whom he is convinced is still alive.
Guile has also been a character in an awful movie adaptation of Street Fighter II. He was portrayed by Jean-Claude Van Damme. In Street Fighter IV, he is voiced by Travis Willingham (better known as the voice of Colonel Roy Mustang on Fullmetal Alchemist).
Person 1: Guile rules.
Person 2: Oh please. Ryu is so much better.
Person 1: Want to fight about it?
Person 2: Actually, yeah.
The only REAL American out there. Those flags on his arms are not tattoos, they're Birthmarks. He breeds Bald Eagles in his plateau of hair, and his guns are not just muscles, they're actual guns. He rides through wastelands on a Bison he raised on Budweiser and the flesh of terrorists.
-Last words before a large Sonic Boom erupted from Guile's Mighty Forearms in Pakistan
Derived from a mispronunciation of the Capcom character of the same name. A guile is another word for 'whore'.
"That chick is such a guile, even _you_ could get head from her."
