Hummingbird Jerk 

1. To masturbate furiously; process by which the human male masturbates so fast that both the hand and the penis become blurred. The Hummingbird Jerk is generally done for one of two reasons:
a. Time constraints; the masturbator has a place to go, such as work or church, but is a compulsive masturbator or has blue balls and has a physiological need for ejaculatory release.
b. Recent extreme physical attraction to the opposite sex (or the same sex, as in Nick's case); due to a mentally inspired rush of adrenaline and testosterone, as well as a throbbing erection, the masturbator gets lost in the process, taking self-gratifiction to the point where penis flesh becomes torn and damaged.

The Hummingbird Jerk is also known as the Hummingbird ("I was in such a hurry that I had to give myself a Hummingbird")

a. Knowing that he could not perform his duties at work with blue balls, Drew gave himself a Hummingbird Jerk so not to be late.
b. "Because I was thinking about Jen's face being covered with my semen, I unintentionally escalated to a Hummingbird Jerk."

circle jerk 

1) Group masturbation, usually males, sitting or standing in a circle jerking themselves or each other off.

2) A fraternity initiation ritual or hazing whereby the lights are turned off. The plege or pledges are told it's a circle jerk. The actives pound their fists together in the darkness simulating the sound of jerking off. The lights are then turned on suddenly and the pledge or pledges are the only ones in the circle with their dicks out.

3) A useless discussion or meeting involving mental masturbation whereby the egotistical, boring participants try to demonstrate they're the smartest persons in the room.

The pledges learned humility from the initiation circle jerk.

after-work-jerk 

The masturbation session that takes place immediately when you get home after a pent-up day at the office.

After staring at my assistant's hot ass all day, I needed an after-work-jerk before I could go to the gym.

Strong Jerk 

When you are riding with a girl in a car and her closest hand to you is her dominant hand making it a really powerful hand job.

Yo, meng I was driving this girl home one night, and since she's rockin' a south paw she gave me that strong jerk.

Minnesota Circle Jerk 

Minnesota circle jerk

When a group of minnesota road construction workers (usually at least 5) abandons the idea that got them into a Minnesota clusterfuck but are now standing around the only actually working person and having a circle jerk, thus backing up and delaying traffic for up to weeks/months at a time. You can tell its a circle jerk from a long ways away because you will notice there orange vests that say MNDoT and yellow hard hats, when you get closer you will notice they are under a tree or leaning on the work vehicles. Sometimes they will have a coffee in one hand and a cigarette I the other. Another possible sighting would be the ass crack out the pants when he is bending over for another can of pepsi

Salina: ok great there's a sign that says"road work ahead," I wonder how backed up it will be?

Apdam: well if its a minnesota circle jerk like usual it will be bad. First you got the minnesota clusterfuck with these guys then the minnesota circle jerk usually follows

Kid in back seat: what's a minnesota circle
Jerk?

Adam: ahh... It's a bunch of minnesota road construction workers standing in a circle under a tree talking about the huge minnesota clusterfuck they just got themselves into.

Kid in backseat: oh cool I want to be in a minnesota circle jerk when I grow up!

Adam: no son your better then that
