A transparent or shady person; Frequent teller of lies and exaggeration of self image. A Kitney may vary in degree, but a true Kitney will lie and exaggerate only to those of the female persuasion. Its use in casual conversation always carries a negative connotation.
"I heard that boy may cheat on you or lie to you, he's a real Kitney!"

"He said his penis is how big? I know at least 12 girls who have had first hand experience and know he's lying. What a goddamn Kitney!"
