I'm quite creative
1.An opener.
"hey does my ass look big in these pants?"
babe: "Say what?"
2. In the middle of the conversation.
"Hey is that cum in your hair??"
3. In the middle of the conversation.
"Hey you're cute.. I think my penis is growing fond of you, literally."
4. If she lifts her head up a bit.
"Here, have a tissue, I think you have a caveman in your nose."
5. If a woman is acting bitchy.
"DANG woman! your ego is so big it has its own gravitational field!"
6. Middle of conv.
"It's been really nice talking to you, so... I forgot my condoms, do you have a couple for tonight?"
I don't expect you to do number 5 since it's lame, good luck man.
