Period Trick 

The process of doing a "Find -> Replace" in Microsoft Word, in which you replace all periods in the paper with a larger size period. This can add one or more pages to the length of a long paper.

I used the Period Trick to make all my periods 14 font and got the extra page I needed to finish my essay!

Best friend to college kids everywhere.

period roulette

When your period is due but you risk going out wearing fancy underwear. Like Russian roulette, but instead of being at the mercy of chance you are relying on your uterus.

Today was day 28 of my cycle but I played period roulette and wore my favourite pants.
