Top Definition
When one masturbates to pornographic material that's extremely perturbing, raunchy, disgusting, or so obscurely erotic that it is hard to consider it "porn".

Perturbation is NOT a synonym to disturbation, which refers to the methodology of masturbation rather than the subject matter.
I was perturbating to A Japanese Woman Fries An Egg And Asks You About Your Day the other day and right after I finished I realized how screwed up it was.

...Then I did it again the next night and came to the same horrible revelation.

Perturbation is so great.

The act of pleasuring oneself whilst anxious or unsettled.
Unsure of when my French train would actually depart, I tried to kill time, but the best I could manage was a perturbation.
