The act of wiping your ass on a motel owning raghead's rag (or towel) after receiving piss poor service there. This would be a follow-up to the classic "Curtain Floss".
The next time I went to the Super 8 in Columbus, I invented Raghead Floss when I ripped "Bob's" rag off of his head and wiped my ass with it when he tried to fuck me over (again) on my motel room bill.
Using the owners towel to wipe your ass after taking a shit or sharting in the motel lobby. This is a nice follow-up to the classic Curtain Floss. Towel Floss is also handy when you drop a Tub Turd.
The next time Ron went to the Days Inn at the Columbus Fairgrounds, Bob tried to fuck him over on his motel room bill again. So he ripped the towel off of his head and used it for Towel Floss.
If someone has traces of sperm still in the mouth after the bj is over, they are said to have "live floss". This term came about after a skank we know had magnified pictures of cracks in her teeth taken at the dentist office, and some stray tadpoles showed up in the pictures.
Don't kissBetty, she just blew Bill and now she has live floss.
