Social gatherings, the teenage ones of which consist of:
+ Tasteless music (see urban music)
+ Those present at them behaving like animals
Teenagers should study and do their homework instead of partaking in such shenanigans.
Some drunken teenagers were partying irresponsibly in the building adjacent to my house one night, so I called the cops on them to protect those naive kids from further poisoning their livers! I'm such an asset to my community. :D
