Overview

Posts about thrembo play out as a mock conspiracy where believers claim scientists are suppressing a forbidden digit between 6 and 7, flipping the "take your meds" schizoposting line back on skeptics1. Urban Dictionary users define it as "an unknown integer between 6 and 7, often touted online as a forgotten/forbidden number," and list Ϫ as its symbol9. The letters ჭ and ∃ also show up in posts, though Ϫ is the one most readers see.

Variants spawned a small vocabulary around the joke. 4chan posters coined "thrembologist" and "thrembonites" in November 2021, echoing the Wumbo bit from SpongeBob SquarePants3. Common formats include an angry red-faced "I ♥ Science" Soyjak defending mathematics, pill-time edits where the viewer must swallow the truth about Ϫ, and greentext screenshots recapping the "does it exist" argument4.

An anonymous user posted to 4chan's /qa/ board on August 11, 2021 with an image of a red-faced "I ♥ Science" Soyjak and the text, "There is NO number between six and seven called 'thrembo.' Thrembo does not exist. Take your meds"1. Replies from other anons called thrembo believers schizos as the thread filled with ironic takes1.

The joke may riff on "Derf," the imaginary number between 5 and 6 that Carly invents in the iCarly episode "iTwins" to prank her math tutee Chuck3.

How to Use This Meme

Thrembo posts typically take one of two angles. One side writes as true believers who claim Ϫ is a forbidden digit scientists suppress, often with pill-time or forgotten-knowledge visuals6. The other side plays the angry "I ♥ Science" Soyjak who tells believers to take their meds1. Variant words like "thrembologist" and "thrembonites" fit into bits where posters claim expertise or membership in a cult around the number3.
