Masturbation to user-generated pornographic videos, viewable on web sites such as www.xtube.com. Unlike offline or partnered masturbation, which is often begun intentionally with the goal of a relatively quick orgasm, xtubation is generally begun unintentionally, or as an escalation of online voyeurism. Many xtubators attempt to delay orgasm until they find a video worth serving as a final destination.
I had no intention to xtubate last night, but before I knew it, I had spent an hour xtubating to my friend's favorite videos, and now my mousepad smells funny.
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
