Pretty unlikely. I can't remember the last time I heard anyone use it aside from talking about the actual animal it refers to.

It is a bit dated as slang in 2025.

I caught that too. Interesting set of examples. I can think of a profane use of beaver immediately, but not a unvalenced use of "asshat."

I think it was an intentional and good example to demonstrate that 0 means unlikely, not impossible.
