A word used by jealous partners when they want to mockingly ask if their partner is being in some way emotionally unfaithful in their interest in another person. Because it sounds jokey it allows them to express their jealousy without being accused of being weirdly clingy.
GF: Steve is really funny, don't you think?
BF: Oh I get it. You lurve him, don't you.
GF: (laughing) what, no! He's a friend.
BF: Yeh you totally lurve him.
"Love is too weak a word for what I feel -- I lurve you, you know, I loave you, I loff you, two F's, yes I have to invent, of course I -- I do, don't you think I do?"
When you feel so unbelievably amazing about somebody that love doesn't seem to do it. It's the greatest feeling in the world, and you'd take absolutely any opportunity to be with the person you lurve. Staying up late at night thinking about them, staring into their eyes to escape reality, longing to hear their laugh, see their smile, feel their hug. You can't compare lurve to anything else, so unless you lurve someone you can't imagine the feeling. If you lurve someone, you know.
