Appy polly lollies is a future slang word for sorry or apologises. Can be found in futuristic books such as A Clockwork Orange. In the future working-class teens, or "nasdats" will say it but for the moment it is mainly the well-read middle-class who are trying to show off by knowing such phrases.
Girl: I boke your phone. Appy polly lollies
Girl 2: What?
Girl: I mean sorry. You wouldn't understand.
Girl: Ugh future slang just doesn't make you cool okay?
