About 10 years ago, I was at a birthday luncheon for one of my co-workers.  It was attended by several of my fellow co-workers, many of whom I knew were gay.  At some point, I responded to someone's statement with, "oh yeah, THAT is so GAY!".  I forget exactly what the discussion was about, but I'd used the word "gay" to essentially mean "stupid" or "ridiculous".  It was a slip up on my part, and not something that I was or am particularly prone to saying.  Of course I felt terrible right after it slipped out of my mouth, as I knew that the lady directly across from me was a lesbian.  She takes no shit off of people, so I was relieved when she didn't immediately call me out on my remark.  "Perhaps she didn't hear me?  Even though I have a loud, booming voice, is it possible that she didn't hear me as it is quite loud in here?", I thought.  Then in a flash, the ditzy blonde to my left, with the big tits who I hoped I might soon fuck, turned to me right as everything got nice and quiet, and said, "I missed it; WHAT is soooo GAY?"!  I, of course, said nothing and tried to ignore her, but I knew I was busted.  Later on, I pinched her thigh under the table and gave her my "evil look".  After the lunch, I explained the situation suspecting that she didn't know that quite a few people at the table were gay.  To my surprise, she knew and even mentioned one other person that I didn't know.  Turned out that she was quite the callous one.  This boded well for my hopes to fuck her (I really didn't like her personality, but her body was near perfect), as I eventually did at a later date.  Despite her hot body, she was not very good between the sheets.  There's probably a few lessons that I should've learned throughout this, but I'm pretty sure I failed.
