thin pick 

1. Used to describe annoying scene kids that suck at playing musical instruments, guitar in particular.

2. Mall rats that spend their nights hanging out in music stores, annoying everyone around them.

3. A more subtle way to describe fags.

No one likes thin guitar picks.

These thin picks are annoying the shit out of me. They suck.

Yeah let's kick these fags out of here!
