Hey, IckySticky...

Oooh, icky and sticky.

Are you coming out today to uphold the law?

I think I know what Tokosan is always talking about.
He's always meant "butt sets".
A butt set, also known as a goat, is a test set for telephone lines commonly used by technicians in telephone exchanges and outside plant. There are many different butt sets, but all of them share a few things in common:

* A rotary dial (for older models) or touch tone keypad in order to dial telephone numbers.
* Receiver
* Mouthpiece
* Talk/Monitor toggle switch
* Test leads, such as alligator clips, heat coil adapter or pins, to interface with the telephone system.
* A removable hook for placing the butt set on a tool belt. It can be moved to the receiver side, mouthpiece side, or removed altogether based on the technician's preference
