The kind of relationships between two same-sex persons (occasionally happens in TV-shows) that gives to girls all over the world a gulp of desire and this sweet madness every time their beloved characters do this. Sometimes fandom can be born just from the eye-sex.
When you establish eye contact with an opposite sex hotie in a bar or party for a long enough period of time that you know you might not come back home alone at the end of the night.
-Dude! I just hade eye-sex with this hot girl! You've got to come with me and take care of her friend!
- How come I always get the fat chick!?
- Do I really need to answer that?!?
the act of holding a passionate gaze (eye sex) with someone from across the room without wearing any protection; such as eye glasses, sun glasses, or contacts.
