2. An extremely misguided person who says "I love you" to every person they have ever had remote feelings for. This person uses the phrase "I love you" like it means absolutely nothing, therefor can easily be related to someone who sleeps around and has sex with people who don't mean anything to them, otherwise known as a slut- thus the title, an "I love you" slut.
Rachel: Wasn't he only with her for like a week?
Bree: Exactly. He tells every girl he dates that he loves them. WTF?! I don't know if I should believe it when he says it to me!
Rachel: Damn girl. He sounds like such an I love you slut. Don't believe a word he says he's just telling you what you want to hear.
