This spelling of the word originated in a gay magazine called, "XY" in the early to mid 1990's. XY is targeted at gay male teenagers. This spelling describes a youthful, hip, and attractive male. While completely embraced in the gay community to mean any young, sexually attractive male, this spelling also appears in heterosexual contexts to mean similarly, a young, handsome guy.
