Doing a Jonno 

When promises or prior arrangements are broken or not kept despite protestations.

He/she has said they're going to join us, hopefully they're not doing a Jonno and not going to show.

doing a jonno 

When you play video games from 1pm - 5am every day and only ever talk in discord when you feel like it.

The phrase can also be used when smoking the good stuff ;)

Example 1:
Jeff: Hey bro where's smile?
Steve: Idk, probably "doing a jonno"
Jeff: My name jeff

Example 2:

Dicky: Yo i'm currently "doing a jonno" if you know what I mean...
Mark: No one asked my man, anyways pass that shit over.
