A man a woman keeps around for platonic favors and services as well as for attention. He usually sticks around in the hope he'll some day get with her.
A guy who secretly loves his female 'friend', and may go out of his way to accommodate her (couch-mover). Either the guy was shot-down early on and was placed in the friend-zone, or he never had the balls to ask her out and inadvertently placed himself in the friend-zone.
A beta male who stays within a close proximity of a female or females in hopes of eventuallygetting lucky. The Beta Orbiter's tactic is to befriend a female, and proceed give her constant attention via text message or in social gatherings. She keeps them in the friend zone, but a beta orbiter falsely believes he is making progress. He may often trash talk other man she tries to date, claiming that she "deserves better".
Beta Orbiters or men who are cucked up, find themselves befriending women who most likely have daddy issues.
A guy who pussyfoots around a specific woman, or women in general, in hopes of getting laid. This almost never works out, as he stays around her dawdling, ogling, and daydreaming rather than actually approaching her.
The orbiter sat patiently as he watched her. Then her boyfriend came along and he knew he had to go.
