A vicious sexual maneuver whereby one plunges the thumb deep into an unsuspecting sphincter while in the doggie-style position. This technique typically produces a savage, wolf-like howl from the recipient. The practice of saying "night wolf" at the moment of impact, while commonly regarded as proper etiquette, is not strictly required.

Although the night wolf maneuver was officially conceived and developed some time in the 2010s by Chris Pankewicz, in Columbus, Ohio, it is widely rumored this technique was first deployed in ancient times by Odysseus as a measure to repel sirens.
Me: Dude, what's that girl still doing here? I'm pretty sure I heard you give her the night wolf last night.

(Shrugging his shoulders)
Chris: She must have liked it, I guess.
