A woman who provides a male show host (primarily in radio) with occasional, or sometimes frequent input and conversation on the current topic. Usually a producer or news reader, she is rarely credited formally for contributing to the show but is always on the cusp of chiming in.

A sidechick can be present from the outset of a show, but usually is added in when ratings drop to increase female demographics.
"I like this guy's show but who is that girl that he keeps talking to in the studio?"

"Oh, you mean the sidechick?"
