a bum flap is wen a girl has a really really short skirt, thats rolled over so many times, its like a really thick belt, and so instead of being a skirt .. is a bumflap! (you see the link...), i.e. nothings left to the imagination, especially on a windy day...bumflaps are very common in secondary schools with the *were not even gonna hide were desperate for a shag* kinda girls
