When two guys sleep together for comfort they are Nightbros.
Tom invited me to spoon when he was staying in the spare bed in our mutual friend's house. I was uncomfortable with the idea, but nothing sexual was intended, he just wanted me to be his Nightbro.
When a straight dude sleeps beside a gay guy and nothing happens besides sleep the whole night.
"Tell me about Losing your Pink Ribbon again."
"I lost my Pink Ribbon to Steve last night"
"The gay dude. No sex? You sure?"
"Yep, just sleep... maybe some spooning."
