look up any word, like sex:
A musical artist who frequently appears on the hook (chorus) of other artists' songs within a genre, particularly hip hop and R&B.

Guy: Hey, did you hear that new Akon so-
Kanye West: Yo, Imma let you finish, but Nate Dogg was the best hook guy of all time. OF ALL TIME!
