I'm going to miss that handle. Big Ten, I know I've called you at least eleven ten different things over the years, but I always revert to "the Big 10leven" in a pinch. With your pending twelfth member, the name will quickly lose it's relevance, so it's best to retire you now and work on a more accurate replacement.
Bonus: EDSBS, what do you like? Big 10welve doesn't sound very good, and if you slur it, like say, after a day of drinking, it just sounds like "Big Tuhwelve". That's going to end up causing confusion and deflect attention from the mis-name. Big Integer has been in rotation already. Should we just bump it up to the go-to nickname since it covers all* possibilities?
Double super-bonus: Is the Big 12 the Big 12leven until further notice?
*Note: Big Integer does not cover partial and irrational possibilities
