my best ever chat up line was when id aslready been speaking to a girl and i wanted it to go further- so we were sitting down and been talking for a while so i looked at my watch and said "right we've been speaking about half an hour you've not tried to kiss me once. Your obviously a lesbian" so i got up as if to walk away and she grabbed me and said "i didnt know i was meant to make first move!"
so i said "yeah you are!" and that was it! BAM! she was all over me!
