Top definition
An unemployed loser who moves back in with his/her parents after dropping out of school, quitting his/her job, breaking up with a girl/boyfriend, and generally failing everything that he/she attempts. This individual may be delusional, and unaware that he/she is, in fact, a rinkster.

This may occur because the individual has no grasp of the functioning of adults in the real world, or simply because he or she is utterly pathetic.
"Dude, did you hear Joey didn't get a job, broke up with his girlfriend, spent other peoples' money, did drugs, and dropped out of school?"

"Holy shit! What a RINKSTER!!!"

"Yeah, but somehow he still loves himself. What a delusional cocky bitch."
