When your friend or group of friends leave you to hang with a newer cooler friend, and stop giving you the same treatment. (ex: stop inviting you to partys, or stop hooking you up with girls).
A Toy Story reference as when Andy stopped playing with Woody to play with Buzz lightyear, making Woody feel salty as hell.
All you wanna do is hang out with jocks now that you're on the football team, man you're fuckin buzz lightyearing me!!!
