A sister phrase to the popular "Freshman 15" that refers to how fat Senior girls get due to excessive partying and beer drinking during their final year in college.
Guy #1: That Holly girl used to be hot right, what happened to her? - Guy #2: She let herself go and gained her senior 15 like a fat slob, what a shame.

After getting accepted into college, high school seniors may experience this. It is when students stop caring about high school and become extremely lazy, more so than someone with Senioritis . These students often skip school or come in late, or not even bother with work. Often they become addicted to video games like Modern Warfare 2. There is no cure except the end of school.
Student 1: Where's Matt? He hasn't been here in like a week?
Student 2. He got into college. He's played MW2 for the entire week. He's living the Senioritis Lifestyle.

A house with a large number of bedrooms (usually 9-14) on a college campus made up of mostly seniors that are in the same fraternity. It is used as a place to hold parties since many fraternities are supposed to be dry (alcohol-free). It is different from a fraternity house in that it doesn't have a dance floor, a large living room, is not old and made of brick/stone, and it has way less bedrooms.
Joe: dude , are there any parties tonight?
Matt: yeah man at XXX (fraternity).
Joe: oh nice, at the fraternity house?
Matt: No, at the senior house.
