A doiter is a stomach on a male that is larger than it should be in respect to the other body dimensions. It generally sticks out moreso than down, and that is what separates it from the beer belly. It is a close relative to the boiler.

A DOITER is a person who doits. They tend to Doit often, and, when they do, they doit to an insurmountable extent.

The act of neither geting on or off my dick and loitering somewhere in between.
