Bring roses, chicks dig flowers.
Next, jam them in her meat vase. Chicks dig practical guys. It means you're going to duct tape the shit out of that burst pipe before the house turns into Atlantis.
Then, when done, whip the flowers out again ASAP. Chicks dig when you remember the little things like their birthdays.
Remember step one - roses? Important choice. If you did the last step correctly, she should be bleeding. Now you go down. Instant proof that you aren't selfish and will be there to deal with her desires and make her feel great no matter what.
Instant marriage, thank me later. I'll get my best man speech ready.
