When a male is so good at the fornication, that he is able to undo the female's pants and his own with one hand, thus being able to still grope and cop a feel with the spare hand.
"Mr. Gossett was such a good lay that he could undo my jeans while fondling my booby at the same time!...Magical."

A woman with only one available hand that works as a hairdresser. You often feel overwhelmed with fear that she'll do a crappy job, and frankly it ruins your day.
Jon: Hey Bill! How'd you like your haircut?
Bill: I dunno Jon, I had the damn one handed bandit working today...
Jon: Fuck...
Bill: I dunno Jon, I had the damn one handed bandit working today...
