Similar to an upper decker, however the turd is taken in the upper tank of a gravity fed toilet (those which the tank is suspended 6ft up). When flushed the turd is sent flying down the pipe fed by gravity and makes a large splash similar to that of a log flume ride.
"Woah! Man I've just been log flumed!!"

The log flume is when you take a dump on someone's chest, and urinate on the chest shortly after. As you urinate the excrement will slide down the chest and stomach the same way a log would.
Ashley was an extremely kinky girl. Everytime I saw her she wanted me to give her the "Log Flume"

The Reverse Log Flume is when A girl is balanced on her shoulders and upper back with her legs bent towards her face. A guy is fucking her in the ass while she is shitting and pissing on her own face. The Reverse Log means the girl is geting fucked in the ass because a log (or shit) comes out of the ass, but since the guy is fucking her in the ass its going back in, hense Reverse Log. The flume part actually goes with Log Flume or an amusement park ride in which you get splashed with water in your face at the end. Hense the pissing in her own face part.
