A request from an onlooker to use a computer or entertainment system to achieve something the requester wants. The word first was coined as a shorthand term to request fast-forwarding through commercials or other unwanted video on a TiVo, when the holder of the remote control had either disengaged in the program on the television or merely forgot they were watching a recording. (The TiVo system gives "clicky" sounds when the fast forward button is pressed, and it's usually pressed two or more times to quickly zoom past commercial breaks.)
1) "Hey, it's the toe-nail fungus ad again; clicky-clicky. Come on, you've got the remote and this isn't live TV-- clicky-clicky!!"
2) " I was trying to clicky-clicky with the website to order tickets but the site was overloaded and my transaction failed; we'll have to pay a scalper for tickets."
Bleary-eyed tourists, generally asians, that take pictures of absolutely everything. The name is derived from the sound their cameras make.
I was going to do downtown to do some school shopping, but since it's still summer we've got clicky-clickies everywhere.
