when your legs chafe together to produce a scab-like chafe. it is very uncomfortable and sometimes occurs on the beach when water or sand goes on the part where your legs rub. some other occurrences are in the summer when wearing shorts, a dress, a skirt and you get sweaty and your legs rub. it's usually for fat people, but average people get it too.
michelle: yo kait, are you chafing?
kait: you have no clue man, its turning into a scafe!
