Masturbation in a lake, ocean, or swimming pool and afterwards collecting the pearls of jism, as if diving for treasure or pearls. This method of sexual self-gratification increases lung capacity and you are immersed in lubricant.
Zach, when pearl diving in the school swimming pool, forgot to collect the pearls of jism so he got our gym teacher pregnant.

Eating an Asian girl out. Stems from the fact that most oyster pearls come from Asian countries which employs a lot of citizens to go underwater and collect pearls. A slang term, but not a mean one
I went pearl diving last night on this fine ass Asian girl named Kiki.
