1. Someone (male or female) who says "I love you" so often and to so many people they have dated that the phrase has completely loss meaning when said by them.
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.
Bree: Dylan just told me he loved me. I would be happy except he also told my friend that he loved her too when they were dating.
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.
