OK, I guess I'll have to argue against. Please don't make component names whimsical. Your idea of whimsy and fun is potentially confusing or (worst case) offensive to others. Yes, make them unique and searchable. Yes, make them memorable and pronounceable. Yes, make them SFW.

It would get tiring to have to keep explaining to new team members that our prime number generator is named "optimus" even if it was initially clever.

I don't look forward to convincing my boss we need to pull in "libAnimeBabe" as a dependency even if it's the best parser for a file format we need to import.

Nobody wants to find out a year after all of our marketing material is put together that our software name means "asshole" in another language.

Don't make me have to pronounce an unpronounceable Gaelic word every time I do a presentation on our software stack because you're Irish and just had to name your component that way.

There are lots of ways "whimsical" can backfire unintentionally. Save your creativity for the actual software solution.
