What does bunk mean?
Bunk most commonly refers to a narrow, often fixed bed or berth, especially one of two or more stacked one above another — the kind found on ships, trains, military quarters, hostels, and children's rooms. The word carries no strong connotation in this sense and appears frequently in everyday phrases such as 'top bunk', 'bottom bunk', and 'bunk beds'. A second, informal meaning — chiefly American — uses 'bunk' to mean nonsense or insincere talk, as in 'that's a lot of bunk'. This figurative sense arose in nineteenth-century American political life and remains widely recognized even if slightly old-fashioned today. Related forms include bunkhouse (a building with bunks), bunkmate, and bunky. The word is useful precisely because it spans both concrete and abstract registers: practical in describing compact sleeping arrangements, colorful when dismissing something as worthless talk.
A built-in bed or sleeping berth, typically one of two fixed one above the other, as on a ship, train, or camp.
"The sailors slept in bunks stacked three high along the ship's wall."
(informal, chiefly US) Nonsense; insincere or exaggerated talk.
"He dismissed the report as complete bunk."
Shortened from 'bunkum', which itself derives from Buncombe County, North Carolina.
(informal) To sleep in a bunk or share sleeping quarters; also (British, in 'do a bunk') to leave hurriedly or abscond.
"We can bunk down here for the night if you don't mind the floor."
Standard plural, used when referring to multiple sleeping berths.
"The cabin had four bunks along each side."
The 'nonsense' sense of bunk traces back to a North Carolina congressman whose long-winded speeches were said to be 'for Buncombe' — his home county.

Etymology of bunk
The bed sense of bunk first appeared in American English in the early nineteenth century, likely adopted from a Scandinavian source related to words for a sleeping place, though its precise origin remains uncertain. The nonsense sense has a well-documented origin: it derives from Buncombe County, North Carolina, after a congressman's lengthy speech made around 1820 was explained as being delivered merely 'for Buncombe' — that is, to please his constituents rather than to accomplish anything. From this came 'bunkum', shortened over time simply to 'bunk' in the sense of empty or insincere talk.
