Earlier quoted context omitted.
So if nothing else it's shockingly bad semantics. If Android called them Turds, would that be any better or worse semantically?
A "toast" means a few words of salutation. That's the purpose of the Toast UI element. A user requests an action, the action returns a successful response, the user receives a message consisting of a few words announcing the success. Just because you are oblivious to the concept it doesn't mean it's bad. It just means you need to learn something before blindly asserting that stuff you don't know and are not familiar…
Out of all the reasons why they could've named it "Toast", the most reasonable one to me would be "because it's another kind of a pop-up notification, and the phrase 'pop-up notification' is already taken".
