The act of one friend using pre-existing, platonic rapport with another friend's ex or otherwise closely connected individual in an attempt to get play and/or sex without having to meet and deal with new people on their own.

Often a trait of sexually inexperienced peoples who prefer that their friends do the work of courting a girl/guy while the "vulturer" lays back and wait for the relationship to fail so that they may move in under the guise of "friendship".

Ironically, "vulturing" nearly always fails in its employment as the concept of one friend taking advantage of another friend's failure is a sign of insecurity and romantic incompetence on the part of the "vulturer". This, obviously, is universally acknowledged as unattractive from the perspective of any potential mate.

This definition also applies to friend-with-benefits and to a lesser extent, siblings.

The act of driving around a parking lot looking for people who are walking to their cars to get their parking space.

When you are eating people are hovering around you waiting for you to finish eating so they can eat the rest of your food. They are vulturing.

Vulture as a verb can signify circling around something, as a vulture would do. For example, the sentence "Rudy vultured when asking the girl out" implies that Rudy hovered awkwardly around her for an extended period of time before making his move.

Art of doing nothing, and waiting for the correct moment to ask your friends for their work/homework/tests answers or whatever they've been working for a long time, with a lot of effort.

For being a good engineer you'll have to dominate this art. When you master this art, you could be called "Sir vulture".
