screensuck 

To waste time on the Internet.

I screensucked on porn instead of doing my homework and still managed to feel productive. :)

Screenshocked 

When someone takes your phone and changes the screen photo to a picture of themselves.

1. Dude 1 says "what happened to my phone?" Dude 2 say "looks like you got screenshocked!"
2. Watch, I'm gonna screenshock a picture of me on my moms phone.

Screenjack 

while looking at one's computer, the surprise pop-up ad that appears independent of the user's actions. typically, this pop-up ad appears to block out the whole screen, and is difficult to close out.

"I was checking out that new website for shoes, and I got screenjacked with an ad for an online university."

Screenhack 

To sneak a peak at an opponent's screen, when competing in a multi-player, online environment, e.g. Call of Duty, in order to find out where they are so you can go shoot them. Screenhackers are the subject of much finger-pointing and deriding upon discovery.

John: "You're looking at my screen you cheating son of a wh*re"

Fred: "No I didn't, I was just checking my watch"

John: "I so caught you screenhacking!"

Screenlicker 

Someone whose tongue is sticking out on their picture or icon on your phone. Every time they message you, it looks like they are licking your screen. Not to be confused with the below average and desperate window licker. A screen licker is a whole 'nuther level of licking!

When he messaged me, it looked like he was licking my screen.... he is such a screenlicker ;)
