hub caps 

Hub caps is bro code for a woman's nipples or areolas. The circular nature of the areola along with the central nipple,or "hub",combined with the surrounding nipple bumps (montgomery tubercles or "auxillary nipples") tend to resemble the wheel or hubcap on a truck or car.This illusion is further enhanced if the nipple is pierced with a barbell making it look like a cotter pin in the "hub" place ther to prevent the nipples from flying off during wild,rough sex or exotic dancing. Along this line,puffy nipples could be referred to as "baby moons".

Dude! When that stripper peeled off her top,I saw the most awesome set of hub caps ever!

hub caps 

The word "hub" can be abbreviated to "huge ugly bumps" which are found on a woman's areola plus the word "caps" can relate to the little black circles that some women have decorated around the areola because they look like bullet holes.

Guy 1: Man, you see those circles around her areola? Look at the bumps too!
Guy 2: Yeah, she got hub caps.
