Not All Pee Pee Times Are Poo Poo Times
Also known as: All Poo Poo Times Are Pee Pee Times · Pee Pee Poo Poo Axiom
"Not All Pee Pee Times Are Poo Poo Times" is a humorous pseudo-philosophical axiom pointing out that while every act of defecation involves urination, not every act of urination involves defecation. First posted on Reddit's r/showerthoughts in July 20191, the phrase picked up steam through anime-themed image macros before exploding on TikTok in late 2022 when a dramatic voiceover reading turned it into a viral audio trend2.
Overview
The meme centers on a deceptively simple logical observation about bathroom habits: every time you poop, you also pee, but you can pee without pooping. Framed like a philosophical axiom or mathematical proof, the statement's humor comes from applying serious logical reasoning to something deeply mundane. The phrase spread first as text-based image macros on Reddit before finding its biggest audience as a TikTok audio clip, where creators paired the dramatic reading with footage of pets looking contemplative or confused.
On July 21, 2019, Reddit user MagnoliaFan42 posted to the r/showerthoughts subreddit: "All poopoo times are peepee times, but not all peepee times are poopoo times"2. The post collected a modest 32 upvotes over the following years but stands as the earliest known appearance of the phrase online1. The format of the observation, structured like a logical syllogism about bodily functions, fit perfectly with r/showerthoughts' brand of oddball revelations.
Origin & Background
How It Spread
How to Use This Meme
The phrase works in a few different formats:
- Text post or caption: Drop the full axiom into a conversation, group chat, or social post as a fake-profound observation. Works best delivered deadpan. - Image macro: Pair the quote with a character or figure who looks like they're sharing deep wisdom. Anime characters, philosophers, or serious-looking animals all work. - TikTok sound: Use @mrhamilton's dramatic audio reading over footage of a pet, child, or person looking contemplative. The humor comes from the mismatch between the serious delivery and the silly content of the statement. Pet videos, particularly dogs staring off into the middle distance, tend to perform best with this sound.
The key to the joke is the contrast between the formal, logical structure and the bathroom-humor subject matter.
Fun Facts
The original r/showerthoughts post only got 32 upvotes, but the exact same words pulled 1.4 million likes on TikTok three and a half years later in a different format1.
The meme's logical structure mirrors a real concept in set theory: poo poo times are a proper subset of pee pee times.
@winston\_da\_ween's dachshund video gained roughly 66,000 likes per day during its initial viral run1.

Senpai of the Pool edits:
The r/animemes version placed the quote on the "Senpai of the Pool" template, where an anime girl dispenses wisdom from a swimming pool[1].
Berserk edits:
The r/berserklejerk community applied the axiom to panels from the dark fantasy manga Berserk, creating an absurd tonal clash between grim artwork and potty humor[1].
