iLicker 

An iLicker is a person so enthralled with any Apple product that they feel compelled to lick it. It's a twisted french-kiss showing obsessive love for all things Apple.

Mr. Weaver licked the new iPhone box on the day it was released. That dude is a total iLicker.

iClicker 

A system in which teachers/professors can check that their students are paying attention to lectures. A mini question is posed mid-class, and students can answer it remotely using their devices. Most commonly found in US state universities.

"Dude, stop watching Pornhub, the iClicker question is on the board!"
"Oh shit, my phone's not connecting"
"Too late, the answer was C"

Iliker

Someone who enjoys pressing the button "I like" for every comment in social networks, whether or not he really does for real. Generally made for friend-spam or to get someone nervous/angry, also to put the subject back to Earth when the comments level seems to be too high.

Guy 1: "Hey man, have you seen Mr. T's comments on Facebook this week? Seems he likes everything he reads, what a fuckin' joke is that?!"
Guy 2: "Yeah dude, he's the best Iliker I've ever seen, the more he likes, the more his friends hate him."
Guy 1: "So cooooool"
