Commonly known as "BHS" bum hungry syndrome refers to the knickers of a male or female once they have ridden up into the cheeks of the buttocks.
The term "bum hungry syndrome" derives from the idea of your arse being so hungry it has actually stared to eat your
pants...
BHS is frequently caused by ill fitting underwear, specific breeds of underwear cause
chronic bum hungry syndrome, so much so that it
may mature into "starving bum syndrome" these
pants include: girl boxers, high legged briefs and the notorious laced
pants. A note for those trying to avoid BHS...ironically pants purchased from the shop "BHS" (
British home stores) do not cause the disease, though ones bought at Primark do (speaking from personal experience!)
In serious cases when the knicker-line of the BHS is visible from the outside of your clothing, it is at this point that the BHS must be ejected. One advises you walk quickly to an uncrowded area and do the deed, as it were.
Girl: "sweet jebus! Look at the BHS on her!"
