Doot-doot 6-7. It's now a Goal Promo Card you can use in Math Fluxx! You may have heard this nonsensical phrase a time or two in 2025 which is why it became the Dictionary.com Word of the Year.  We don't get it either... but every kid is saying it. The meaning is quite ambiguous, despite 67 being the 19th prime number and also a lucky prime. Still, with all that going for it, why not add this silly and playful phrase as a Goal to Math Fluxx? Yeah, we couldn't think of a reason not to either. Six-Seeeeven!
