I'm gonna leave you to it
The ultimate way to end a conversation like it was a battle you won. Used when you're tired of talking and don't care if they're confused.
'I'm gonna leave you to it', said after being yelled at by your mom for 10 minutes.
'I'm gonna leave you to it', said while walking out of the room like you owned the place.
'I'm gonna leave you to it', said to your crush after they asked you out.
