When a male has to masturbate more rapidly than usual because he knows that someone is coming home soon and he may not have much time to finish before interrupted. The act of "strobing it" is similar to the speed at which a strobe light flashes.
Pete's roommate called to tell him that he would be home in 5 minutes. Pete must begin strobing it at a higher rate of speed in order to avoid an awkward situation.
