Being envious of the size and/or resolution of someone else's computer monitor, television, cell phone, digital camera or handheld video game console screen size.
Dude, I just bought this new 17" with 1024x768 resolution, but I got total screenis envy when I saw the new Apple 30" cinema display with 2560x1600 resolution.
Guy 1: Hey guys, I just bought the new Samsung GS3.
Guy 2: And I just bought the new iPhone 5...but jeepers, your screen is so much larger that I have screenis envy comparing the two.
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 ;)
