app
Shortened form of 'application.' Popularized by Apple Computers Inc. with the introduction of the iPhone. Mainly implemented because the majority of the Apple userbase is too retarded to even be able to use two mouse buttons, let alone pronounce a four syllable word.

app
Abbreviated form of "application", a type of software program that typically interacts with the end user, such as a calender program or a chat program. Applications differ from lower-level software programs such as device drivers which are mostly invisible to the user.

Since the late-2000s, the term "app" has been bastardized by Apple and other Apple wannabes to specifically mean a software program that you can buy at the "App Store" or variations thereof. In fact "applications" have been freely available online since the advent of the Internet and this concept is completely foreign to the majority of "app" buyers.
Jimmy: "check out this social app I bought from the app store yesterday!"

Apps (or app/ application) is programs/games most likely being downloaded to a smartphone, computer or iPad.

When you first have downloaded an app - there is no way back, you will get a strange love relation to apps like "Angry Bird" and other games/programs. Your phone bill will explode and ruin your whole life.
"DUDE! Look i have just downloaded this app - Angry Birds on my new iPhone"

-OH GOD! You are all ready lost.

"say what?"

or:

"Hey dude! Have you seen my Facebook profile today? My new pic's - I'm using my app called Retro Camera. I FUCKING LOVE MY Apps"

Yeah, you have posted like 30 pictures today. Ten of your dog. You have a serious addiction man!

"Wtf!? Tits or gtfo noob"
