BanSHEE? or BanCHE?

While waiting to see Twilight with my mom and sister we had a funny conversation haha Kelly and I realized that we say weird things that other people don't say. Thanks to the influence of our mom and dad. Thanks. haha For example. Hair ties are NOT called "pretties". I still call them these. Thanks mom and dad! haha Then we were talking about different catch phrases we say, and Kel brought up the fact that we always say Banshee. Do we even know what this means? Not really. haha I always grew up thinking it was like a scary ghost that is really fast, and screams? I don't know. But we always use the phrase: "Ran like a Banshee". Then, we realized that we didn't even know how to spell it. And here goes the conversation:

Kelly: "how do you spell banshee?"

Me: "I thought it was B-a-n-s-h-e-e"

Mom: "No...I think  it is B-a-n-CHE"

Kelly: "well...what IS a banshee? I always say, "she ran like a banshee" but what is a banshee?"

Mom: "A crazy Indian" -dead serious

Kelly and Me: "WHAT??? hahahahahaha No way!"

Later we google it. Turns out a banshee (spelled how I thought) is a fairy from Ireland. Like a leprechaun. haha Whatttt? Urbandictionary.com, I think you are wrong!
