Doo Doo Fly 

One of those green flies that spends most of the day sitting on and eating a steaming pile of animal shit, then takes to the air for a final lap around you only to land on your lips or on your plate of food.

Did you see that doo doo fly land right on Greg's lips???!!!

doodoo fly 

A fly that surrounds poop within minutes after dropping it off in the rugged woods. Also, very noticeable from the greenish/blue shiny look on its back.

Note: It is big in size and slow in speed...ie. retarded!

Before I could find a few good leaves, here came those damn doodoo fly(s)!
