Wat

Excreting
Evacuating
Eliminating

And yes, word is the word.

Language: covers words and names

Peeing and pooping: https://www.thesaurus.com/browse/defecate

Excrete is pretty good as your collective word https://en.m.wiktionary.org/wiki/excrete

"use the restroom"

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.

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

Names are words, so "words" refers to both collectively. "Elimination [of waste]" or "voiding" for the second one.

Scat fest. Mob shitting.

Elimination

Names are words. And make up one for the pooping and peeing thing. Something like peeooping, only more proactive.

One word? You should make up one, and see if it sticks.

Suggestions:

• peeping
• definate (pronounced deff-eh-nate)
• jettison
• expel

"1s and 2s"? .. no, not good enough.

How would language have ever come about then?

“Titles”?

If you think "relieving yourself" is disgusting, use a polite white lie.
Just say you're going to the bathroom to snort coke.

If anyone is interested, you can call food and drink collectively "victuals". That's another one I was looking for.
