Reduplicated

Wally hated reduplicated words.
Born in Walla Walla, Washington, he moved to New York, New York.
He refused to play with his yo-yo or go out for putt putt golf.
When he saw a cheerleader with a pom-pom, he’d tear the things up.
When he saw someone with a mahi-mahi, he’d jump on the fish.
When he saw Pizza Pizza at a Little Caesar’s restaurant, he burned the place down.
When he saw someone dancing the Cha Cha, he’d trip them and break their legs.
The cops arrested Wally, he was convicted, and sentenced to ten years in Sing Sing.
