I`d like to know the name of a song.?!

I know it`s going to be difficult because I Don`t any of the words!. I did watch how they danced to it if that helps!. It slows up in the middle of the song and they threw their pelvis forward then back then side to side and then they swung their arm over their heads in a lasso motion while they turned around The chorus was like Ba ba ba ba Ba !. when they did those moves thats how the chorus went!. 10 points if you can help me!.
