Josh: I dunno man, she's got some big hoops.

Mike: What do you mean?

It is a theory about non-black girls involving the wearing of hoop earrings. The theory states the bigger the hoops a girl wears (usually a white girl), the more likely she is to date a black guy. It's usually pretty accurate, although there are always exceptions to this theory.
Sarah has jungle fever and always wears big hoop earrings; this is her signal to men of color that she likes the black D. Lee, a black man, picked up on this and asked her out--they've been dating ever since! Sarah is proof that the "Hoop Earring Theory" is true!

The bigger the hoop, the more a woman likes anal sex.
"I noticed your 5" hoops and wanted some help in a little study I'm performing. It's called the Hoop Earring Theory, which states that the bigger the hoop, the more a woman likes anal sex. Can you tell me if that it true?"
