Not that I think that 'miffed' is the exact word to use, but rather that it's a word that needs to be used more often.
Tonight, one of the gay acronyms (GLBTPSAFTQA ad infinitum is sponsoring a dance. When people ask me "Hey Bob--what are you doing Friday night?" I've taken to responding with "I'm going to Gay Bash," and jokingly refer to it as such-- "It's been so long since the last gay bash. I've really got some pent up energy that I need to work out" or something along those lines.
My roommate is uncomfortable when I say 'gay bash,' and I say that if anyone gets to feel uncomfortable about gay bashes, it's me.
Gay bash gay bash gay bash.
(Yes, I know I'm a bad person, and it's things like this that cause the karma that has left me sex-free for over a year.)
