Definition

The linguistically questionable phenomenon where fully grown adults adopt toddler speech patterns, complete with simplified words and exaggerated inflections. Popular among couples who've run out of normal ways to communicate and pet owners addressing their animals. It's either endearing or disturbing depending on your tolerance for vocal regression.

Example Usage

My roommate uses baby-speak with her boyfriend and it makes everyone uncomfortable at dinner.
