1. (noun) a person who can go several days to a week between evacuating feces at which time the evacuation is often forceful, voluminous and time consuming. The resultant evacuation typically fills the toilet bowl and requires more than one flush if it can be flushed at all.
"Dude, did you see the toilet in the bathroom? Bill just used it and filled it with shit...He's such a poo camel"
"My brother hasn't gone to the bathroom in like a week...then again that is usually often he goes. He's like a camel is with water...in fact a 'poo' camel"
