the act of two persons eyes meeting and usually has a clear indication that they are "undressing each other with their eyes"; always has a sexual tendency. Definately able to excite and arouse all that participate.
"Michelle and Christian were totally having eyesex on the way to chemistry today; just look at the bulge in his pants!"
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.
Jane: And you don't wanna sleep with me..... Do you?
Maura: *dat look full of eye-sex*
