A Porter Blump is a delicate, complex, and rather steamy process through which an individual is receiving fellatio from another individual in an outhouse or 'Porter Potty' while taking a dumpasaurus rex. The receiver experiences an unprecedented rush of pleasure from the act of defecating and ejaculating simultaneously. The giver feels similar to Tom Cruise.
