The sexless innkeeper is when you take what you think is a potential hookup home with you, and they fall asleep on your couch without hooking up. She or he only went home with you because you lived close by and they needed a place to crash for the night, therefore using your place only as an inn, making you its innkeeper. Defined by Barney on How I Met Your Mother.

When you meet a girl with whom you're about to get some but she ends up falling asleep in your apartment, turning you into the sexless innkeeper.
"Dude, I was totally about to get some, but she fell asleep in my apartment and I didn't want to wake her up"
"Dude, you were totally the sexless innkeeper that night!"
"Dude, you were totally the sexless innkeeper that night!"
