The tendency of otherwise straight girls to decide that they're gay during their time at Smith College, only to realize that they're not shortly after graduation. See also smithies
I knew this great, beautiful girl who went to Smith. I had a huge crush on her, but she was gay...or so we thought. Turns out she was on the four-year-plan, and now she's in New York and has a *boyfriend*!
