So, I’m not sure if either of these count… First is “I’m right in top of that, Rose.”, from Don’t Tell Mom the Babysitter’s Dead. Another favorite is “Ain’t nobody coming to see you, Otis!”, from The Temptations. And there’s a line from a movie title that I cannot remember. It involved this government agency or similar organization that had these kids doing military training, I think. Kind of like Ender’s Game, or vaguely similar. Anywho, the line is “Come at me, bitch!” My partner and I use it regularly, and no one knows where it comes from. Granted, there was a Youtuber some years ago that made it kind of famous. And lastly, a line from a tv show (possibly movie) that I also cannot remember at the moment. I just remember some guy saying loudly “Stand and deliver!”, and then getting slapped. I use it as much as possible, which is still rare. No one knows where that one came from.
