The Nightwolf 

Blasting pussy with middle and ring finger while massaging the clit with your thumb in a circular motion. Your pinky and pointer will point out giving you a wolf like hand. It's the art of blasting pussy.

"Dude I unleashed the nightwolf on that girl last night!"

"I nightwolfed that bitch!"

My roommate is a night owl and usually reads until 5:00 A.M. A few night owls stayed at the café all night long.

Night Owl 

People who are assumed to be lazy and/or procrastinators. However, they are the masterminds of Earth.

My Supporting Reasons:
~ Peace and quiet to focus (everyone else is asleep).
~ For all my fellow antisocial homies, no human interactions for hours! WOO HOO!
~ No distractions (i.e. media notifications, sunshine, good weather, people, sounds, etc)
~ More time to enjoy the daytime. Doing hobbies, talking to people, and just acting like a normal human beings in general!
~ Not having someone constantly peeking over your shoulder (that is, if you live with people).

In conclusion, Night owls are frickin' geniuses and deserve more credit than they are given. FYI, I'm writing this definition @3:54 A.M.

Person A: You look tired.
Person B: I am.
Person A: What time did you sleep last night?

Person B: I didn't.
Person A: Damn... you're officially a night owl.
Person B: THANK YOU! WHAT AN HONOUR! :D

Night owl on steroids 

A night owl on steroids is when you stay awake until midnight or later and even until 3am, 4am, or even 5am without feeling sleepy or tired. It's when you're sleeping until 11am, 12pm, or 1pm. You sleep 8 hours and feel refreshed when you wake up around noon or later. You get energized from 5am and even more later. It's delayed sleep phase disorder. The treatment is Modafinil early in the morning to wake up since you can't turn the rest of society into night owls on steroids or even night owls. Treatment also includes taking 25mg to 50mg Amitriptyline at 10pm So that by the time 11pm comes, you fall asleep.

Tony: I have delayed sleep phase disorder. So by taking Modafinil early in the morning, I can wake up early in the morning and stay awake. Then I fall asleep earlier too. I used to be a night owl on steroids. Now I'm an early bird as long as I take Modafinil early.
