give oneself airs

to put on airs or give oneself airs: Fig. to act better than one really is; to pretend to be good or to be superior; to consider oneself above others; displaying arrogance.

What a jerk! Why give oneself airs? She's no better than any of us.

When you'll get enough of giving yourself airs and talking nonsense, the rest of us little people can carry on with the meeting.

On my ones

"On my ones" is a popular phrase used in South East London high schools and is simply slang for “on my own”. As all slang does, the phrase slowly died out and is now used purely for comic effect. Variants of the phrase include: On your ones, Ones and One-sies.

Guy A: I'm just going to go get some chocolate.
