How sway?

[Couch Potatoe]

Reaction to someone doing or saying something that is completely impossible. Unheard of, not realistic or hard to understand.

How Sway? = How is that possible?

How Sway? was invented by Kanye West during his rant to radio host, Sway.
Please see Kanye West and Sway interview: Raw and Real on Sway in the morning
Kanye repeatedly yells, How Sway?
