When you force a person to swallow three fresh ass logs at once in an attempt to make them puke and possible infect them with something. This will only work if said person is someone from Urban Dictionary has posted one or more definitions (rejected or not) that involve consuming feces with possible rough anal sex, otherwise it is just torture.
Seriously people... stop posting disgusting shit on Urban Dictionary! If you are trying to get some form of recognition for something then get your damn facts straight and post a REAL sex position WITH REFERENCES! UD is for ALL audiences not just for you sick little cunts!
