Grunchie

The improper way to spell "Grunchy".
Means "Grumpy and Punchy"

Often spelled incorrectly in this manner by silly dramatic arts majors.

*Thespian Moment*
"I feel so...Grunchie today."

"Yeah, that's not how you spell it."

"But I said it out loud, I didn't spell anything!"

"You're still wrong."
