Originating in Glasgow, Scotland "
night night patter" is when you get to that part of the night when everything
that's not funny becomes hilarious, all whilst needing no explanation.
Night night patter is usually paired with illegal substances such as acid, ketamine and alcohol.
Night night patter in itself cannot be fully defined, however here are some examples I have come across.
Person one - 'mate look at the state of her, she
paints her fucking nails"
Or
Person one - "Know what I'd love? A nice
vegan sandwich and a bit of dick"
