Calling it "taking a poo" is so un P.C.

Heard lots of messing behind a closed washroom door. So I look in and see Eva taking a poo... But messing with the rad and everything else she can reach:

Dad: Eva, what are you doing?
Eva: Havin' a toilet.

This is Eva-speak for taking a poo. Must be the flowery language the school makes them use.
