harm reduction

The practice of providing advice and helpful suggestions to a novice regarding potentially dangerous activities in the hope that they will heed the advice and not cause hurt or harm to themselves or others.

Practicing harm reduction Keith showed Brittany how to IV drugs. According to him he didn't want the wrong person showing her the wrong way, because he knew she was headstrong.

reduction of order 

Reduction of order is a technique in mathematics for solving second-order ordinary differential equations. It is also a technique used in restaurants by math geeks who change their order to an amount less than originally requested.

I went to McDonald's and ordered two Big Macs, but I changed my mind and ordered only one. They didn't like my reduction of order.

Relation Staycation 

When you are so pissed at your significant other that you do everything you can to ignore them for a week or longer, but you are too damn lazy to leave or move out. (It's like a twenty four hour ice, but longer.)

After working all damn day and doing the dishes after dinner, my lazy-ass old woman bitched at me for not cleaning the fucking spoon rest. So I took a week long relation staycation. I fucking hate moving.
