Failasturbate 

The act of poor masturbation which results in a failure or inability to complete the act to obtain an orgasm.

I already masturbated five times to the Golden Girls season three DVD and on my sixth time I failasturbated so I called it a night.

fantasturbate 

when one masturbates so impeccably well that he has a fantastic and accomplished feeling afterwards; when he can look back on that day as a day that was worth living. If one has these feelings, he deserves an award, for he has just fantasturbated.

After a long and depressing day at work, the man came home and felt the need to fantasturbate. After he did, he went to sleep quite satisfied.

Flasturbate 

A verb, meaning to masturbate at speeds exceeding 55 mph. If you ever masturbated in a moving car or on an airplane that was not Flasturbating. It was masturbating in a car or an airplane. Flasturbation has to do with the speed of you hand.

The flash doesn't masturbate, he flasturbates.
