What's a Badonkadonk?

We knew what thunder thighs and blubber were - when the couple orders at the drive-through in the Subway TV ad - but we didn't know what a badonkadonk was. So, to the computer to check it out.

Badonkadonk Definition from Wikipedia, the free encyclopedia:

Badonkadonk is a slang term for a woman's buttocks that are voluptuously large and firm, yet bouncy. Women who possess this feature have a small waist that flares dramatically into round, peach-shaped buttocks with deep cleavage.
The term is based on the imagined rhythm of a sexy gait, an example of non-auditory onomatopoeia.

Originally, the word was hip hop slang. It first appeared in mass media in 2001 in a line by rapper Keith Murray in the song "Fatty Girl": "You got a badonkadonk, girl, don't hurt nobody!" The term gained a wider audience in the fall of 2002 through Missy "Misdemeanor" Elliott's #2 hit "Work It" which includes the lyric "keep your eyes on my ba-bump-ba-bump-bump, and see if you can handle this ba-donk-a-donk-donk."
