What is "Whoopee" ?

If it's "Whoopie Pies", those are made in the kitchen.

Please explain, crisp hi quality images may help.

Any time I have steel that refuses to be drilled I get out an old cement bit.
Put a sharper edge on it and go to drilling. I drilled through a ball bearing just to show someone I could do it.

what do you use to sharpen the carbide wings of the cement bit? I thought it had to be something like a green wheel. And what angle do you use?
