Triscuit’s name has nothing to do with the number of layers the cracker has — it’s actually a portmanteau of two completely unexpected words.
According to the company, its name actually stems from “electricity biscuit.” The snack’s real name was revealed in response to a Twitter thread from writer Sage Boggs.
Several years ago I was at a party (BRAG!), and I spotted a box of Triscuits. I asked everyone, “What does the word ‘Triscuit’ mean? It’s clearly based on the word “BISCUIT,” but what does the “TRI” mean?” (I’m great at parties.)
