to bend a females legs up by her head and then motorboat her vagina
i motorboated your sister last night,

oh yeah, i just finished an oscillating motorboat on your mum

A person, typically on the internet, that easily and hastily changes their political and/or religious beliefs depending on what is popular and fashionable at the time. The reason for the name is to point out that the people are both shallow for lacking any real beliefs and are able to oscillate to another belief, likely and/or eventually to another.
Many people that occupy the political sphere in online politics nowadays can be correctly labeled as shallow oscillators.

when one is railing the mouth of a female cum dumpster and when he is about to ejaculate on her face, he grabs his oscillating fan and he blows his load in the fan shooting cum droplets all over her face.
Last night that random girl from the bar told me i could do what ever i wanted, so I gave her a much needed oscillating facial.

The process of spinning hands in the air to symbolize your sexual desires. The double hand spins represent jerking off and the double hands emphasizes the gay practice of such. This can all be put together when a girl does it to show that she wants to be done by multiple men at once. Typically in the mouth. She has an unquenchable thirst for semen.
Hey stop hand oscillating in Saga! That’s innapropriate!

The hyper-accelerating movement of Earth's magnetic north pole due to the increased presence of densely concentrated methane in the atmosphere.

{Since the early 1800's, scientists have tracked the ongoing movement of the magnetic north pole. The Polarity Oscillation Orbit (P.O.O.) was coincidentally discovered by a globally recognized audio engineer, Sir Laramie Todd and his visionary studio lab research colleague, Duke Robert Rite of Dungville. In the early 1990s, Sir Laramie recorded a new orbital sound waveform stemming from low frequency feedback captured in a Duke Rite bass guitar track. Sir Laramie took the clip from the Duke, triangulated the distinct properties related to the frequency, velocity and peaks of the Duke's clip and recognized that feedback patterns were spontaneously and abruptly profound during the Duke's output, specifically after ingesting a Filibertos burrito and flagilating convulsively in the direction of the speaker. Through his unique study, Sir Laramie proved the effects of methane gas on microphone magnetic fields. The Duke hypothesized that too much methane, when interacting with iron, causes polar instability on a grand scale. Thus, P.O.O. was born with the rationale that human overpopulation and the extensive quantity of excrement, causes the north pole to oscillate in a predictable pattern, with velocity and speed influenced by the proportionate concentration of methane in the atmosphere.
1. The Polarity Oscillation Orbit is expected to extend into Siberia by 2040.
2. Humans are creating P.O.O. because of their poo.
3. Dude, lets dial in the bottom end of the bass recording today. Go get some Filibertos and prep yourself.

A more polite way of saying the "shit hits the fan"
When I went in to see 'The Thing', and that guy's head sprouted legs, I knew the defecation hit the oscillation.

Often likened to Karma, this is the rare linking of two peoples fortunes (or karma) so that when one is up, the other is down. Often in context of sexual exploits or progress with the opposite sex. Often refered to as the OP Effect.
Guy 1: Mate, i am totalling experiencing the OP Effect!!
Guy 2: ahhh the ol Oscillating Potcham Effect
Guy 3: Gutted boyo, you are never gunna get laid now!!
