Get the McDonald's Internetmug. Where cool kids (read: losers with no lives) hang out every day. And by "every day", I mean they get off the bus and go straight to McDonalds and proceed to stay there for hours at a time. Said "cool kids" are unable to get a job at McDonalds, because they're idiots. They also occasionally get boyfriends there. There is the occasional lesbian there at work, and a herd of glaring old people. Note: Do not talk to the lady that cleans the tables!
Girl 1: Hey, do you want to go the Rockspring McDonalds to pick up guys?
Girl 2: That's where I got my last five boyfriends! Sure!
