creepy
1. Eerie or spooky. Whew, that creepy sound turned out to just be a creaky door.
2. Producing a feeling of uneasiness in others due to an unseemly manner or inappropriate behavior. Who's that creepy guy over there who keeps staring at us? If you hit on girls with that creepy pick-up line, I'm not surprised you keep getting rejected.
creepy
mod. eerie; frightening. I have this creepy feeling that someone is just this very moment reading something that I wrote.
