Teach me how to dougie?

Alright so my sister thinks she knows everything. I was talking about "teach me how to dougie" by Cal Swag District. She says it is a "rip-off" of "teach me how to dance" she was unable to give an artist name. She claims "they like play it all the time at the bluelight" and the chorus sounded" exactly like teach me how to dance but all that start stuff sounds nothing like it" so i told her it's probably teach me how to dougie being pkayed and she is mistaking "dougie for dance" I searched and cannot find any song called Teach me how to dance. She says "come to the disco you'll see" I suggested it might be a retarded remix. She told me that it IS a song and Teach me how to dougie is a rip-off. Is she right?
