When a woman squats down on your face and empties her bladder. Her ass cheeks will, if done appropriately, keep her urine out of your eyes just like a set of goggles would. Sometimes an enema might also be involved if you really love each other.
I was freaked when she wanted to do the Japanese Rain Goggles on me, but it was totally worth it.

Japanese Rain Goggles is when a man gets a oral sex from a woman while his testicles are on her eyes. Once he's about to reach an orgasm she blinks quickly giving him a slight tingle sensation to his testicles and increasing the pleasure.
Damn, i hooked up with this chick last night and she did the Japanese Rain Goggles, best head ever.

Fictitious sexual act performed on the TV show Two and A Half Men. In the episode, Charlie Sheen's character refers to his new girlfriend, Jenny McCarthy, giving him Japanese Rain Goggles. In the context you are to assume this is like a Dirty Sanchez, Dutch Oven, or similar act.
She was unbelievable in bed. She just gave me a set of Japanese Rain Goggles, like I've never had before.
