So, this is college, not the real world. Pretty much just being alive and in the same vicinity will get you laid at a college party.
Yeah, I read the topic title. Derp.
If you want to pick up the nastiest, easiest girl there then sure. Also that's much more true depending on how well built you are/if you look good. Like I said, girls are insanely shallow. I was pretty chunky the first couple years of college and it wasnt impossible, but difficult. Once I shed over 40 pounds it became 1000x easier, you can pretty much setup a chair and let them find you.
