A Fuck bunker is a predetermined space within someones house only used for sex and has no windows and is lockable. For instance this may be a cupboard under the stairs or a wardrobe. The fuck bunker can also be used to tie up your wife/husband and leave them in there while you foricate yourself with a corkscrew.
OMFG have you seen the news, the bad weather is on its way. Quickly get the lube and meet me in the fuck bunker.
