How often do you nickname your Pokémon?

I never used to bother nicknaming my Pokémon. I would quickly run out of names and couldn't be bothered.

In more recent games I decided to deliberately nickname the first member of a species I caught and deliberately use an all new Pokémon team as soon as possible (in new generations) to force myself to try them out and experience new things, rather than using the same teams in every game. At least until I finished the story.

The problem with that is that I never learn the new Pokémon's actual names, because I only see my own nicknames and I don't encounter some species enough in the wild or trainer batles to remember them.

Coupled with the fact that I haven't played a Pokémon game in English since XY, it makes it very difficult to discuss newer Pokémon in either language.

It would change every time. For example, if I caught a Chewtle I might associate it with turtles. I would associate turtles with reptiles, then eggs, then omelets. I would keep going until I got to something crazy, like math binders.
