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!

nightfap 

Masturbating just before sleeping. Similar to the way a nightcap can help you relax and unwind at the end of the day before sleeping. Common in young males that have high testosterone levels and need a way to shoot off some steam. Can also be useful in situations of extreme horniness making you unable to sleep.

"I was way too stressed to sleep, so I had a nightfap and slept like a baby."

"Man I was hanging around Julia all day, so I was way too horny to sleep. Nightfap solved it."
