The illusion of a bikini bottom formed by unkempt pubic hair.
A woman who was naked from the waiste down was once walking down the street and I thought she had on a t-shirt and bikini bottoms, but as I got closer, I realized it was a pubikini.

A pubikini is a swim-suit with a V-shaped opening that exposes the pubic area, invented in 1985 by the same guy who created the topless monokini in 1963.
No, she wasn't just showing camel toe on a bikini, she was wearing a pubikini, showing off bare beaver!
