A phrase first coined in MTV show Geordie
Shore, a Buckin Bungalow is a spare room which is separate from the
main building, where
people go to engage in frivolous sexual activities.
Gaz: Just got out of the hot tub, now i'm gonna take her to the buckin
bungalow.
James: everyone's in their
bed, better go to the buckin bungalow.
