There's a hot 18 year old I started hooking up with over the summer, and I just know she's going to get fat now that she's in college.  She's lazy as shit and refuses to exercise and she eats like shit.  Last time I saw her, she was on the higher side of the healthy range (she's 5'8), but I know she's going to pork up in college and I'll have to cut her loose.
