Hwhy? 

Used as an emphatic way of saying Why? to emphasize that the one being spoken to will never get anywhere. This even has a way of provoking them.

Tom: “Todd, would you like to trade your plain snow hat, deerstalker hat and overcoat for my pompon snow hat, baseball cap and jacket?”

Todd: “Hwhy?”
Tom: (provoked)“Because I hate my mediocre winter gear and want to wear impressive winter gear!”

Hwhy? 

Used as a way of letting the one spoken to that they’re simply wasting their time. Saying why like this also has a way of provoking them.

Jake: “Hey, Ben, would you like to trade your seven cupcakes for my six cuppycakes?”

Ben:“Hwhy?”
Jake:(provoked)”Because I hate having only six cuppycakes!”
