you jerk off while taking a shit on the toilet. same as blumpkin but instead of getting a blowjob you engage in self-pleasure

Similar to a Blumpkin except there is no second party involved. The self serve consists of jerking off while taking a dump. The self serve happens much more regularly because you do not have convince a slore to blow you when taking a crap.
Mike muth was on the prowl for a blumpkin but wasn't coming up with a suitable candidate, therefore he had to resort to the classic self serve blumpkin.

I was sitting on the toilet with candles lit and Yanni music playing and got really turned on while pinching a loaf. So i gave myself a Self Induced Blumpkin. The smell of my own poop made me cum into my mouth.
