Much like a dog whistle, however a chimo horn is used to locate child molesters. The mechanism resembles an air horn which emits a blaring rendition of The Entertainer that is only audible to child molesters.

This will of course be invented in the year 2037, during the United States' War On Chimos.

Person 2: What the fuck are you talking about? I don't hear shit.
Federal Agent: Busted, chimo!

(Federal Agent and Person 2 throw their arms over the other's shoulder, and give a hearty thumbs up.)
