I want a word to refer to words and names collectively,
and a word to refer to peeing and pooping collectively (not "relieving yourself" since that is disgusting)
A word for words and names? Nomenclature, terminology, lexicon...
A word for peeing and pooping collectively? Most words have other uses, but also pertain to both bathroom activities, like Excretion, evacuation, expulsion, waste, elimination... There are better words that specifically refer to each act individually, but not collectively. Just for peeing there's urinate and micturate, and just for pooping there's defecate.
I work outdoors, often in remote locations. Phrases I have used:
Make friends with a tree.
Speak with a tree/have a conversation with a tree.
Commune with the bushes.
Wander over this way alone.
My field partner often speaks of watering or fertilizing the forest, which I find distasteful because it gives a sense of which act they're performing and I really don't need to know that about my boss.
But you couldn't say "Bob" and "throw" are both "languages". You can't say both are words either... (can you?) They're a name and a word, respectively. Is there another term perhaps for either a word/name (rather than a general concept for what they're part of)?
In games I play, we call it a "bio break" or just "bio" because it can also include getting more water or snacks, or stretching after sitting for a little bit
