KeyBot. Name describes what it does, and is short and "friendly."

Call it the "chunk" that's pretty much how simple it is haha. Just a chunk of useful metal.

Living on the TX/MX border for the last 20 years, when someone has a tough time describing something, they call it a "Chingadera" slang which best means, the thingamajig....so that's my .02

I have to say, I like the "Herc" suggestion, but I was thinking that it looked like one of those sculptures/ heads on Easter Island... Not sure what name follows.... Beer-head, Open-idol, Tiki-key... You are welcome to use any of those or whatever inspiration may come from my observations. I've been looking for just that sort of thing lately!
