A tramp stamp that covers the entire width of a woman's lower back.
Coined from the
words "whore" (natch) and "oriflamme," which means a banner or standard that serves as a rallying point. In this case, a rallying point for douchebags, guidos, et al.
Also known as a
slag flag or bint banner.
"
Dude, what's with that girl's back?"
"She's showing off her whoriflamme. Won't be
long till she's surrounded by douchebags."
