The area of ocean which otherwise would simply be a part of Pacific Ocean were it not for Japan's presence. The term "East Sea," recently coined by ignorant Koreans to replace "Sea of Japan," is neither appropriate or accurate, and has obviously nothing whatsoever to do with "Japanese occupation" during WWII, which itself is a total hoax.

When you bang a girl in a hotel room when she is on her period and leave a huge red spot that looks like a japanes flag on the sheets.
Oh man the people in room 212 just left me a huge japanese flag.
So did you make a japanes flag last night??

a "japan flag" is the stain created on white or light coloured fabric, often on bed-sheets or underwear, when a total bottom has been railed bareback up the ass by a footlong and bleeds from their butt profusely
"That dude fucked me so hard last night that I woke up and my bed looked like a Japan Flag!"
"I had cheeky bum sex in the janitor's closet with the Quarterback, and he want in raw and rough, so now my ass is bleeding and my underwear have a total Japan Flag situation going on"
