When the "Sassy Man Apocalypse" meme blew up on TikTok in October 2022, thousands of users had fun showing their "sassy" boyfriends, typically showcasing them displaying feminine or "sassy" behaviors.

The trend is going viral once again, this time with the addition of a new internet slang: "deriod."

The slang is confusing some people on the video platform, as the playful twist on the idea of "men's periods" is inspiring them to post hilarious videos recreating clips and gestures of American rapper Saucy Santana, the singer of the viral "Material Gworl" song.

Let's unpack the origin of the "deriod" slang term and the return of the "Sassy Man Apocalypse" meme on TikTok.

What Does 'Deriod' Mean On TikTok?

Deriod is a slang term and portmanteau that humorously combines the word for men's private parts (think slang that starts with "D") and women's "menstrual periods," with the idea that men can have that too, creating a satirical term suggesting that men, like women, can experience mood swings, attitude shifts or emotional changes (often exaggerated for comedic effect).

The term gained popularity after a TikTok user @abdoulupnext posted a video in March 2025 jokingly claiming that "guys also have periods during certain times of the month," with the caption referencing someone being on their “dihriod” (a variation of “deriod” using the slang "dih").

What Is The 'Sassy Man Apocalypse' Meme?

Before deriod went viral as a popular slang on TikTok in April 2025, men's mood swings were jokingly called out during the "Sassy Man Apocalypse" meme, which started in August 2022 on Twitter / X.

Over time, TikTokers adopted the phrase to showcase their own "sassy" boyfriends or friends, often with videos of men acting confidently or cheekily, captioned with phrases like, “Victim of the sassy man apocalypse.”

How Is 'Deriod' Used In Memes On TikTok?

TikTokers quickly added "deriod" to their lingos, often using the term as a punchline or caption to humorously depict men “going through” a period of moodiness or attitude, usually paired with GIFs, videos or voiceovers showcasing sassy behavior.

For example, in April 2025, TikTok user @shyyxlew posted a video adding overlay texts featuring "deriod" and other funny phrases used in the Sassy Man Apocalypse trend, expressing her disbelief and amusement at the slang and catchphrases created for the meme.
