Coast'splaining

When a smug west coast or northeast coast liberals talks over or tries to 'splain to liberals in the south. Often in a condescending and holier than thou manner.

West Coast Liberal: "I'm glad hollywood is pulling out of the south"

Southern Liberal: "That's only going to hurt us"

West Coast Liberal: "If you don't like it, you should just move"

Southern Liberal: "Maybe I want to stay and fight... stop coast'splaining!"
