|“||Gretchen, stop trying to make 'fetch' happen, it's NOT going to happen!||”|
Fetch is a slang term Gretchen Wieners often uses and tries to 'make it happen'. The word's actual meaning is supposed to be 'nice', 'expensive' or 'cool'.
The slang became extremely popular with the Mean Girls' fandom and to this day, after 14 years as of 2018, people all over the world are still trying to make 'fetch' a real thing.
Along with 'You go, Glen Coco!', 'fetch' is by far the most memorable term from the franchise.
Regina: [referring to Cady's bracelet] I love it!
Gretchen: That is so fetch!
