Define Ass App Meaning

Ass App
An ass app is terminology commonly used by graphic designers when having to urgently create something from scratch or figuratively 'pull it out of your ass.'

Client: "Oh, we love the ad campaign but would like to make a few changes. Could you change the photo, rewrite the copy and have it to the publisher in an hour?"
Graphic Designer: "Sure! No problem. Let me use my ass app and I'll have that ready in a jiffy!"
