When a minor evil has occurred but is so lame it couldn't be the devil himself. It's Dan, the lowest level of demons incapable of true evil just stupidly annoying. When things like that happen you say in a disgusted tone, "Thanks Dan" it's a way of saying you didn't really get me but you are a dumbass.
Someone is stalking you, and has listening device in your home, yet is able to get everything wrong. SMH "THANKS DAN!
