1. The act of being very sketchy towards other people.
2. The act of making people feel very uncomfortable because of your overbearing and stalker-like nature.
3. Trying to get a girl or guy that you have no business trying to hookup with but trying to anyway, making the person and everyone else around you very uncomfortable, yet very entertained as well.
