havin' a lovely time

(Has to be said in a Northern accent, ideally Yorkshire)

That feeling when you're surrounded by your best friends/family/lovers/everyone in between with good music, booze and dancing. You can pick and choose from those elements, but there will be a perfect cocktail of them for you that means this saying just comes out.

Friend/lover/cuz: Y'alright?
Me: I'm havin' a lovely time...
