What's wrong with "urinate" or "pee"?

“Oh freddled gruntbuggly,

Thy micturitions are to me,

As plurdled gabbleblotchits,

On a lurgid bee,

That mordiously hath blurted out,

Its earted jurtles,

Into a rancid festering confectious organ squealer.

[drowned out by moaning and screaming]”

—Douglas Adams, The Hitchhiker’s Guide to the Galaxy

It is quite interesting to note, that when I read this as a teenager, I did not even try to find out what “micturitions” are, because I confidently assumed that these were all nonsense words.
