Listening to angry music really loud
Ah jeez, sometimes it's just the best. Not generally when I'm actually angry though (rare occurrence really and I don't think I'd make it back to my yard to angst out about it lol). Furious tunes from your youth? :D 3 from me...
D-12 - Fight Music
Rage Against The Machine - Guerilla Radio
Slipknot - Eyeless
