Describes a specific kind of casual gathering between two or more individuals. More often times than not, the sharing of alcoholic beverages is involved during this very relaxed event.

The phrase is meant to recall the sharing of a drink with another person and simply enjoying one another's company or possibly engaging in a deep and meaningful conversation, all while sitting on a rooftop.
"Would you be up for some liquid therapy tonight?"
"Sure! What do you have in mind?"

"I don't know really. Small group hang out? Something pretty rooftop casual."
