MSB

MSB is an abbreviation for Magic School Bus, the classic animated TV show and book series about a wacky science teacher, Ms. Frizzle, who takes her students on wild educational adventures. The term "MSB" began to appear in online conversations, memes, and nostalgia posts during the late 2010s and early 2020s, as millennials and Gen Z audiences looked back fondly on shows from their childhood.

Fans use "MSB" as shorthand when referencing the show's crazy science lessons, Ms. Frizzle's iconic catchphrases, or the show's unpredictable field trips, like shrinking down to explore the human body or blasting off into space. You'll often see "MSB" used on social media platforms like TikTok, X (formerly Twitter), and Instagram, especially when people joke about wishing they could "MSB" their way out of real-world problems. The term is most popular among people who grew up watching The Magic School Bus in the late 1990s and early 2000s, but it has also received a new wave of love in the 2020s thanks to reboots and memes.
