I went to a club last night, they played a line dance song, it wasn't a country song, but they lined danced to it, male singer, lyrics go something like "down down baby... help! Would love to know who it is:

If we are listening to the same song it's the Cupid Shuffle by Cupid!

Country Grammar by Nelly

Starts out:
"Hmmmmm
I'm goin down down baby, yo' street in a Range Rover (c'mon)
Street sweeper baby, cocked ready to let it go"

-I'm not posting all the lyrics due to explicit lyrics-
