TBH, I've seen pretty much every age group (apart from OAPs, who are far more subversive, and excellent at playing the innocent) ****ing around while drunk. I've seen 15 year olds start the "I want to hit you but I don't want to get hit" fights that seem to come in 10 second bursts, interspersed with "Get 'im!" and "he's not wurf it!" from their loud girlfriends who probably got them in trouble in the first place, to 40 year old blokes stealing traffic cones and hitting each other with them, aswell has harrasing other drunks at 3AM (being acccosted by a traffic cone wielding drunk is not a very nice experience, it was in good humour, but still, dogs have probably pissed on that), and everything in between. It's worse in Spain, where the rules don't seem to apply anymore.
