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"

Get the Manny’s flagmug. That annoying bit of toilet paper that sticks to your ass and waves like a flag after you get off a public toilet that you have lined with toilet paper to keep your ass clean and free of ass cooties. It can also be formed when you wipe your asshole with toilet paper and then it unfurls in your fingers; one end remains stuck to your asshole while the other end dangles freely from your hand.
I had to shit in the outhouse and lined the toilet with TP so I wouldn't pick up ass cooties. When I finished and stood up, I sported a really annoying butt flag that was hard to remove. One time I even wore one home and didn't know it until I removed my underwear; fortunately, my wife didn't notice it.
