Star girl

The kind of boring girl that is not willing to do lot of things or she is not willing at all. The word star, as a reference to a girl in bed doing nothing but the star and waiting for the guy to do the whole work.

Friends : Hey! Wanna grabs couple of drinks with us tonight? the exams are done!

Star girl : Oh I can't! I have to start working on my assignment due for next week...

Friends : You're such a star girl
