Great Barrier Reef 

A big reef off the coast of Western Australia, that is currently get its colour fucked sideways and its turning completely fucking white.

Person 1: (being born and raised in Western Australia) Damn, have you seen the Great Barrier Reef lately? It's almost completely white!

Person 2: (being born and raised in the US, not really giving a fuck) Huh, needs to tan, I guess.
Person 1: It's a piece of fucking coral.
Person 2: Still needs to tan, though...
Person 1: *walks off*
