These kids also think it is fun to t-bag everything, to bunny-hop, camp, and generally play like a bunch of n00bs. The whole time they cuss, often depending on the word "Fuck".

What really makes them annoying is their prepubescent voices. Constantly hearing the fuck word from squeaky voices is enough to drive you mad.
