An icky is a creepy old guy who is always seen in the same spot (Mcdonalds, Walmart, A sidewalk, etc.) and hits on women, usually high school girls, though he sometimes goes for soccer moms.
How about we go to Mcdonalds for lunch?
Let's go to Burger King instead. Last time I was there an icky kept staring at me. It was sooo creepy.
Have you seen the icky who always rides the subway on Wednesdays?
Yeah, last week I gave him a fake cell phone number and told him my name was Stacie!
