A good icebreaker is: "asphinctersezwhat".
One that works for some people, but for some reason did not work for me... I was in a bar one time, and I was watching this guy approach women. It took him about 2 tries, but he got a girl to leave with him.
He approached the girl and said, "Tickle your ass with a feather?"
She responded "WHAT?"
He said, "I said 'Particularly nasty weather.'"
Then they started talking, and they left together.
So I thought I'd try it. Being my first time, I must have messed up my delivery.
I walked up to a woman and I said: "Shove a chicken up your ass?"
She said "WHAT?!"
I said "####in' rain..."
I didn't get her to leave with me
