A hole is a hole
A way to sleep when you have to be next to another guy, like in a jail cell or when you're being forced to sleep with your brother.
'I slept like a log next to my brother, and I didn't wake up until noon.'
He said, 'I had to sleep with my dad, and it was like a nightmare.'
She texted, 'I slept next to my brother, and I can't even look at him anymore.'
