Post a pick up line. The person below you rejects it by saying something funny/witty/mean. Then they post a new pick up line. Example:User one - If I could rearrange the alphabet I would put "U" & "i" together.User two - I bet you can't even recite the alphabet in its correct order. Did you get any bruises.. When you fell from heaven? I'll start! If beauty were time, you'd be eternity.
