nightcat 

A method of keeping your head warm on cold nights, by allowing your cat to curl up on your pillow, the back of your neck, or your head itself.

Buddy: It was really cold last night, wasn't it?
Me: I dunno about *you*, but *I* was super cozy with my quilt and nightcat. He purred me to sleep, too!

Furness-Nightcap 

When at the end of a night out drinking you offer a goodnight hug to a female friend and attempt to slip a finger in her anus.

I gave Jenny a sweet "Furness-Nightcap" before she went home last night!
