Mean Girls The Musical: the essential glossary

All the fetch words and phrases you’ll need to know before Mean Girls The Musical hits the West End in 2024

There’s a time-honoured tradition of teen movies creating their own language – think Cher’s “I’m totally bugging” in Clueless or Veronica’s “How very” in Heathers. 2004’s Mean Girls just might reign supreme as the most quotable teen comedy of all time, and the 2018 Broadway adaptation only expanded upon that legacy, with its soundtrack introducing plenty of new phrases to the Mean Girls dictionary. Behind on your North Shore High vernacular? Don’t worry – with Mean Girls the Musical set to arrive on the West End in summer 2024, you’ve still got plenty of time to memorise our handy glossary. Securing your tickets, however, is something you won’t want to wait on…
