To describe your problems to a rubber-duck or other inanimate object. Common in software development, the act of describing your problem (as to a mailing list, friend, or a rubber duck on top of your monitor) often leads to finding the solution just a few moments later. In the mailing list case, rubber ducking would then be to mail the list again saying "Ok, that was dumb, but now I'm stuck on the part where...", then to discover THAT solution immediately after hitting SEND. Repeat, ad lib, fade.
When we got back from dinner, it was getting hot and heavy fast. The thought crossed my mind to grab a condom, but I figured there was no harm in doing it one time without protection. I was rubber ducking for like 20 minutes in my head.
It is a term for ball tapping. It is also used to describe the act of slapping a woman's breast to inflict pain. When one does either one of these action they must scream out Rubber Duck or Rubber Ducked. The first person to ever ball tap someone under the new name was NK from Pennsylvania at about 4:30 p.m. The first time a breast was slapped under the name was about 10 min. later by a KP from the same state. (Caution: Check local and international law before performing Rubberducking as it may violate them. Rubberducking may cause cancer. Please Rubberduck responsibly and enjoy.)
