Premature checkulation 

When someone checks you in on their smart phone before you've actually arrived at the establishment

Hey Lola, I saw on Facebook you checked me into the Bulldyke Lounge while I was still 30 minutes away. What's up with the premature checkulation?

Premature Clickulation 

When you fast forward through the commercial on your DVR and stop short before the commercial is finished in anticipation of the commercial being over.

I got a little excited and experienced premature clickulation when I was watching TV last night so I saw the ends of all the commercials.

When I was fast forwarding my DVR I had some premature clickulation... the commercial wasn't finished when I was!

Premature echeckulation

When a waiter/waitress brings the check to your table even though you are in the middle of eating your meal and enjoying your drinks.

Wayne, "Is that the check for our meal? I'm still eating my steak and I want to order another drink."

Julie, "Yeah, it is another case of premature echeckulation."
