Rubber Bones

When you feel so tired or relaxed that your bones feel like rubber/jello, and all you can do is just wiggle (kinda like those balloon guys at the front of a car dealership)

Guy One: Hey man, why tf you wiggling like that?
Guy Two: Oh sorry, I got Rubber Bones

Rubber Ducking 

The act of rationalizing unprotected sex/not using a condom when one or both parties are not ready for a child.

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.

Rubber-banding 

The handicap given to CPUs in racing video games when one or more human players is ahead. This often plagues the less experienced human player, as they will be passed up by CPUs moving absurdly fast in an effort to maintain close proximity to the farther ahead human player.

Jordan is always so far ahead in Mario Kart that I need stars AND mushrooms just to match the speed that rubber-banding gives to the last place CPU.
