Similar to slimey, but with an air of innocence and similar to kiss-ass, but with out the obviousness. Typically, a male, who gives brief but strong focussed attention to a number of females, often in the work-place, that is drippingly sweet, but carries the occasional lame sexual innuendo that is immediately retracted by a childlike expression. A man, usually a co-worker, or person in contact with large group of female potentials, with puppy-dog eyes, offering an insincere concern and easy compliments, who has (not-so-)hidden agenda accompanyiing his actions and conversation. Easy to discern for the experienced or for those who trust their intuition. Preys most easily on young and vulnerable. Is not harmful, but had own best interests at heart, which usually involve sex, or in the very least, creating self-directed admiration.
"I heard that the new supervisor from the new store is real smarmy."
"yeah, I met him, he's really 'nice' n' all, but yeah, he will smile and give you a little fake charm and feel you out to see how far he can take his comments and then he'll whimper that you don't like him or sing that you are the best and he'd do anything for you, all you need do is ask. I can't stand it when he comes around, attention seeking, because I look like I'm being rude, but he is so smarmy it repels me."
"I knew a smarmy guy once, ewww.. all my friends couldn't stand him either and the guys all thought he was a bit of a nerd, but they didn't really understand that he was smarmy."
"I had to explain smarmy to my ex-boyfriend, one night, after he introduced me to his co-worker who kept asking me personal, leading questions, hoping to create a trust and then find a loop-hole in my faithfulness to my guy."
