"Baby Talks Dirty" is a 1980 Top 40 single written by Doug Fieger and Berton Averre from the Knack's second album, ...But the Little Girls Understand. Like the album it was taken from, "Baby Talks Dirty" fell short of the success of its predecessors.

The Knack was an American rock band based in Los Angeles that rose to fame with its first single, "My Sharona", an international number-one hit in 1979.
