It refers to the character Ted Mosby in How I Met Your Mother. At the end of Ted’s perfect first date, he tells her, “I think I’m
falling in love with you.” This was a habit Ted couldn’t break. So every time someone said “
I love you” too soon, it was known as pulling a “Classic Schmosby.” And sometimes you later realize that you weren’t actually in love — you just really wanted to be. It’s okay to fall in love, but don’t say anything until you’re sure that’s what you’re really feeling, and wait a
little bit. Don’t rush these great times, these beginning stages where you get to know someone and sometimes you can’t even look at them directly because they’re so goddamn cute.
