From The Urban dictionary: Patches O'Houlihan.
You are having sex with a girl, reverse cowgirl style in her wheel chair, on an incline. As your finishing, lift her by her lifeless hips, and toss her in front of the wheelchair, and proceed to run the bitch over. The best part about this technique, is she'll still be there tomorrow. But if you're a gentleman, you'll call her a cab.
"So I gave this girl a Patches O'Houlihan, and I was going to call her a cab, but she got hit by a semi. At least I got the wheelchair out of the deal."
