The Groms

Pussies who hang out at 800 and act tough. They only jump kids 10-1 because in any fair fight they would get their ass beat. They pull up to parties univited even though no one wants them there. Complete fags.

Should we go to that party? No because the groms are prolly gonna crash it and they are all fags.
