an act similar to that of the standard shit dick, but instead, in this case the male has diarhea and having the sloppy feces go all over the toilet. for this act to result, the man must also drop a rather large-in-mass turd, causing the diarhea from earlier in his defication to backsplash on his penis. this resembles a shit dick but with sloppy, wet poo instead of water that backsplashes.
i ate a lot of chineese food the other night, had diarhea and got a major shit dick supreme.
