to say that you have or that someone else has a booty like that of Jennifer Lopez (a famous Puerto Rican actress/singer/fashion-line owner)

Personally i think she's a great actress but a horrible singer and the only reason she has a fashion-line is because of the hundreds of much more talented designers she can afford to hire and steal their credit. Just like her ex-boyfriend Sean "P.diddy" Combs a.k.a Puff Daddy.
