A man with sugar-lips can easily be identified because of his fine, glossy lips, and an uncontrollable and almost unconscious propensity for licking them.
Please note, as a general guideline, that while all men with sugar-lips are gay, not all gay men have sugar-lips.
Homosexual man: Oh pleease. He's definately got the sugar-lips, hun.
Examples: Keith Olbermann, Tom Cruise.
