When something is/was waaaaay more than just poppin'.
To denote that something was the very essence of hype, live, fun, wild, sick, maybe even as a result of being Turnt Up
Poppin + hippopotamus (cause they are hella' BIG) = Popanopolous (Something that was poppin' off in a BIG way!)
- Shit was straight popanopolous over at Mikes house.
- That nikka Don Deezy keeps things popanopolous all day er' day.
