mutt

1. informal A dog that is a mix of breeds. That old hound is just a mutt. I think he's part spaniel, but I have no idea, really.

2. slang By extension, a person whose ethnic heritage is multifarious. Potentially offensive. My father is from Canada, but his own parents were from Japan, while my mother is South African with some Dutch heritage on her father's side. So, yeah, I'm a bit of a mutt.

4. slang Deaf. The term comes from rhyming slang in which "mutt" is short for "Mutt and Jeff," which rhymes with "deaf." Primarily heard in UK. Can you please speak louder?

1. dated slang A nickname given to a pair of people, especially friends or partners, who have distinctly contrasting qualities, especially in height.

A regular Mutt and Jeff, they were.

2. dated slang A method of police interrogation in which one of two interrogators behaves in an overtly aggressive and accusatory with a suspect, while the other acts much more supportive and sympathetic.
