A: A plastic horn that makes an obnoxious, droning, buzzing sound. Much like soccer (football) fans trying to argue that their 300 year old sport is relevant and/ or interesting.
B: The mouth of a soccer fan. Typical of 13 year old boys going through puberty.
Good old boy #1: Did you see that man-boy stuffed in the toilet at the bar last night?
Good old boy #2: That was awesome!
Good old boy #1: Yeah I put him in there. He kept droning on about how great FIFA is so I stuffed him in there. I asked him nicely to keep his vuvuzela shut but he refused so I put him in the shitter where he belongs.
Good old boy #2: Thank you, you are a great American!
