A person or couple (gruelers) who tries to push him/herself into a social scene that is beyond their status or out of their social norm - ending up taxing the whole party.

Also a person who tries too hard to be friends with a specific group of tight knit friends and does not fit in.
Justin: Yeah, I just got a new H2 after I got back from Whistler and it barely fits in the garage of my new 5 BR House in Stratville. You'd think they'd design garages bigger. You been to Jackson?

Regular: I've been out there, it's nice. Excuse me. (turning to regular chick) "what a freakin' grueler."
