A social event, when random people from multiple circles of friends assemble to party (and/or chill) and drink. The best random drinking is unplanned and spontaneous. Also, random drinking is usually BYOB and its not uncommon for a fight to break out.
- What are you guys doing later tonight?
- I don't know, probably just hangin' out...maybe some random drinking at my buddies place...we'll see what happens.
