Is it do a poo or have a poo?

[Dogissue]

What do you say?

I say neither because I never mention these things.

What is correct english language wise?
If you're doing a poo, you're doing something so that makes sense. Having a poo sounds like you're eating it.. But then we say 'have a shower' don't we? Not do a shower. I don't like when people say 'I'm going to get a shower' (is B&Q open)?

Sorry. I'm having a day off from life today and this just sprang into my head. Humour me please.

@Dogissue

ginandwine my stepson used to say 'curling off a log'!

My brother used to say he was ‘crimping off a length’ or ‘laying a dog-egg’ 😂😂😂

Bowel opening.....
But then I don't tend to announce it.

We say we need to defecate and we’re hoping for a 3 on the Bristol Stool Chart.
