Why isn't this a doodle?

[Jane, Rooney & Stuart]

Dumb question (and I did search this but couldn't find anything).  Maggie is Rooney's best friend at our dog park, she is a Cockapoo.  Cocker Spaniel + Poodle  so why isn't she considered some type of doodle?  I think she is a Cockerdoodle.  I realize that this sounds a bit nasty and most people might not want to say that they have a Cockerdoodle but really isn't that what a Cockapoo is?  So can someone please explain - what defines a doodle?  If there are Labradoodles, Goldendoodles, Aussiedoodles, why not Cockerdoodles or would that be a Cockadoodle?  Yes, I woke up in the middle of the night to ponder this - lol.

Maybe the last one is too close to a  " cock a doodle do "  chicken!

I've always used "poo" for smaller poodle mixes and "doodle" for larger poodle mixes. I don't know why...just easier in my head!
