Generally discovered around 2pm, a "Nasty Light' is a can of Natural Light partially consumed the night before that still has about three quarters of its contents remaining. You really want to dump it out, but it seems like a shame because it is a reprehensible waste of alcohol and there are 14 of them scattered around your apartment.
1. God damnit, those assholes you invited over last night left Nasty Lights all over the place. Yeah, whatever... put them in the fridge, i guess.
2. Dude, you gonna hit some of that Nasty Light tonight?
