fecal gas 

The really putrid gas that comes out of your ass after you have had one in the chamber too long. It is the gas that picks up extra stench because it has to work its way around a big old brown trout waiting to spawn freely.

Jesus Christ Tom - got some fecal gas or what? Think maybe you should take a dump and spare us from the next one!

When one takes a shit so nice that they enter a state of euphoria.

"Joe why did you lay on the floor for five hours after you took that shit?" "I had a fecalgasm"
