In class everything is normal until these mother fudgers show up and ruin it all.
Example:

Everything be nice and peaceful for working on some assignment or just hanging out (kinda) then suddenly when these guys think it's too boring they make the loudest noise or start talking to their friends really fucking loud which causes the rest of the class who's working and starts to get annoyed by those kids turn their volume up a little more. It's better than hearing some stupid stuff from their mouths and you feel brain cells fizzing out from stupidity. (Not calling them all idiots but their acts are the stupidity part)
