An act - either a by-product of poor hygiene, or as a precursor to the bombing of Hiroshima (bomb Hiroshima) - in which an Asian subject deposits a large dump in a cubicle which typically receives only Caucasian use.
Optionally includes the laying of a "dollop" on the toilet seat.
Man, I invited some of A-town over on the weekend and they utterly destroyed my bathroom. ..
I had no idea they were going to bomb Pearl Harbour.
GENERAL: Private VanHorn, why the fuck are you late to formation?
PRIVATE: Sorry sir! Major Propnuts, Captain Silverbars and I were giving Hiroki a Pearl Harbor until 4AM!
GENERAL: Carry on, Private.
When a Japanese guy lives on a higher floor in an apartment building than an American girl and they're both on their balconies. He starts masturbating on his balcony, then jumps off right before he comes, faces the building, and jizzes right when he passes her floor, giving her a surprise pearl necklace as he falls to his death.
When your sleeping next to a chick who has her back to you and you start to massage her back and act like your just being nice to her for no reason, and then you just hit it from the back while she least expects it. You see, its a sneak attack which hints the name Pearl Harbor. She willnever see it cumming.
My chick is all pissed off at me because I gave her the pearl harbor while she was sleeping last night.
