This week, our intern Kristine deGuzman, a junior at UC Berkeley -- pictured above with her boyf -- bemoans the effects a significant other can have on one's quality college partying.

I frat-hopped every weekend of my freshman year. Once Friday rolled around, I would whip out my knee-high, lace-up, black leather boots (that were completely impractical any other day of the week) and strut my way in and out of various fraternity houses. I would drink, dance with random guys, go home, and then do it all over again on Saturday. In fact, my dorm floor pretty much knew it was the weekend if I was wearing my knee-high, lace-up, black leather boots. It was a predictable routine, but oh, how I enjoyed it.

That is until I got a boyfriend and we fell victim to the phenomenon known as "couple's stamina."

I was first introduced to the term during an episode of How I Met Your Mother. It refers to how couples drastically differ from single people at parties. You can always tell who's single at a soirée: they drink like it's an Olympic sport, mingle like the Ebola virus, and dance like they're on MTV's Spring Break coverage. Couples, on the other hand, arrive at a party and immediately look for somewhere to sit. They relax for a while, talk mostly to each other or other couples, yawn occasionally, and then leave the party pretty early to go home and watch TV, have sex and/or sleep. Thus the term "couple's stamina."
