Switch 

A friendly game where you and friends put one finger in your mouth and another up your butt. When someone says switch, you switch fingers. Forms of “Switch” can be played with varying peoples mouths/butts. And you can even use different fingers each round.

You: “Hey, Joe wanna play a game of switch?”
Joe: “Sure thing bro!”
*one finger enters mouth (preferably pointer finger of one hand)
*another finger enters butt (preferably pointer finger of other hand)
Joe: “SWITCH!!!”
*fingers switch

suck switch 

Any random piece of hardware, software or even something hidden in firmware or the UI that is easily flipped, and no logical person would expect to force a system to stop working. And yet, it does. Making the system un-suck is usually much harder to find than the aforementioned switch.

"Why does my wifi no longer work? I can still reach it on my phone".
"Oh, there's a little switch on the side of your laptop that shuts it off. A lot of people hit it accidentally".
"Well, that's a suck switch!"

Blue Switch 

The act of transferring a phone call from your smartphone to your car's bluetooth system. The phrase can replace the somewhat verbose run on sentence that typically describes the transfer process.

Hold on while I get in my car and transfer the call to my car's bluetooth speaker.

Sorry about that, the call was switching over from my phone to my car.

Hold on a sec while I blue switch you.

Sorry, just blue switched you.
