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!

Verb: To leave a social engagement without saying goodbye to anyone, avoiding small talk, hugs and peer pressure to stick around. Usually accomplished with a trip to the bathroom and then spinning away silently into the night. This is never used to avoid a check, only to avoid a late night and possible DUI.
I was getting tired and decided to hubcap when I saw Joe buying another round of shots. I went to the bathroom and rolled from there.

disgusting balloon looking tits that have massive nipples resembling car tires and hubcaps, the nipple is the same color as the boob and is a horrifying sight, it is a significantly mentally scarring image, they are often seen on girls with massive boobs that they can't stop showing everyone, because that's all they have to offer
holy shit, i'll never like huge boobs again, some girl just flashed me with some nasty ass hub caps
