nipple knife

A nipple knife is when a females nipple gets really hard and could be used to cut open a potato or any other hard object a knife can handle.

Last night my girl friend had her nipple knife out cutting the potatoes and slinging them into the hot boiling water to turn them into mashed potatoes.

A better way of saying you're gonna cut yourself.

Me:I'm gonna do a knife trick
Friend: Don't do that! I care about you!

knife twister

One who kicks another while they are down. A person who latches onto another's insecurities and makes them feel worse.

Did you hear what Brittany said to that homeless guy about his life sucking - that was a real knife twister.

Man, Brittany is a real knife twister.

Knife Forker

Placing the blade of a knife through the tines of a fork at a right angle. Reminiscent of a slingshot or catapult. Best when accompanied by shooting sound effects.

My son Jack entertained himself at the restaurant last night by making a knife forker with his silverware.
