Just another word for clickety clackety; that is making noise through typing on a computer keyboard.

Jason: *clickety-clack* The Sword of Shannara! That's the first book in the Shannara series.
Laura: What about the author's other series about the lawyer who becomes a king?
Jason: *clickety-clack* The Magic Kingdom of Landover. Here, take the keyboard. The library search engine is quite easy to use. What is yet another series by that same author?
Laura: *clickety-clack* The Word and the Void.

Clickey 

A hickey given to a woman on her clit. Clit+hickey=a clickey

I was going down on my girl & sucked too hard on her clit & gave her a clickey.

Cookie Clicker 

A game that consists of a cookie that must be clicked repeatedly to make more cookies. It gives you the illusion that you are making cookies, but you are really not. Tumblr seems to be obsessed with it (around August 2013)

Tumblr user 1: OMG have you played cookie clicker yet, it ruined my life!
Tumblr user 2: What no but I'll check it out
Tumblr user 2 after playing Cookie Clicker: OMFG I CAN'T STOP CLICKING THIS COOKIE

clickety clackety 

The sound of a number of keyboards being typed upon in an otherwise quiet office.

You could tell it was a busy time in the office because of the lack of conversation, and incessant clickety clackety going all morning.
