This app's been available for a month now, but I'm willing to bet few of you had heard of the darned vuvuzela horns before the weekend just gone. If FIFA actually bans them, here's your free app replacement.

The app description promises to "annoy everyone in sight, in the pub, wherever...whilst watching your favorite football team etc getting thrashed." It's free, and has iPad support for double the irritation. [iTunes via Mobile-Ent]
