a nasty, red, painful, sometimes bleeding, open wound as a result of a typically centralized, rubbing motion between two rough and/or non-lubricated surfaces. often occurs during doggy style sex, on the knees of the receiver, from direct carpet to knee contact.
We fucked doggy style on the carpet last night; now I have such bad rugburn, it's hard to bend my knees.

When, during vaginal intercourse (or the attempt at) in the missionary position, the male's lower umbilicus area (the area below the belly button) as well as the surrounding abdominal region, are penetrated by the female's stubbly, three-day-beard-like pubic hair. The repeated, thrusting movements of the male eventually lead to "rugburn" - conventionally a reddish, rash-like discomposure of the skin. Warning: In certain cases, rugburn can yet create skin ruptures and cause minor bleeding.
"Bro, look at my lower stomach area. It's completely swollen and dark red. Golly, I knew having vaginal intercourse with Aunt Shelly would be wrong in many ways, but I never thought she'd give me rugburn."

similar to a "puck-slut", a "rugburn" is a member of the female sex that is in close association with social events sponsored by rugby organizations and often perform sexual favors for members of the team.
