Bunk in?

What does "bunk in" mean? I am sure if it's "bunk in" or other similar sounds. I thought it means two persons sleep in one bed.

I don't think that it means two people sleep in one bed. I think that it is more likely to mean that it is time to go to bed.

I think it means sleeping in spare beds (especially bunk beds) as a guest in someone's house, probably for a short while.

I thought it meant "to batten down the hatches".

all right. So is there any phrase means two persons share a bed?

According to wikipedia, in British English, to "bunk up with someone" means to share a bed. However, I haven't come across any online dictionary that has that definition. All I've seen are a bunch of sites that says that bunk-up is British slang for having sex.

Merriam-Webster has "to occupy a bunk or bed: to stay the night"

double up - v. share a room or a bed designed for only one person

"bunk with" (sharing a bed or a room with someone)

ok, maybe it's "bunk with", just like Vic said.
