A term for the effect that Tegan Quin has on girls. She can cause straight girls to question their sexuality, gay girls to go crazy, and straight guys to wish she were straight. This is because of her amazing talent, witty humor, and overall sexiness.
-Dude, Meg's been posting lots of pictures of Tegan Quin on her tumblr, and she says she's kind of in love with her. But I thought she was straight...?

-Oh, that's the Tegan Effect.
