Zūmbāe
A zūmbāe is a person who does the excersize of zumba so well they become a master at it and are so qualified as a master that they can teach a jazzersize class on the rip off asian copy of "excersize at home" DVD. If a zūmbaē wants to be extra then they will dance to Olivia Newton John's song "Physical" which will really get them pumped and ready to direct their class.
Me: Wow our instructor is so good at excersizing
Friend: yeah don't you know that she's a zūmbāe
Me: ooooh makes sense
