Bitches who don't wipe down equipment when they're done sweating all over it! One time my friend and I were waiting for 2 machines next to one another to open for us....when they did, I cleaned the one I was on and the one I was going to use, next to my friend. I walked away for 2 seconds to throw away the paper towels and out of nowhere this little fat fucker waddles over to my machine and puts her water bottle on it. When I came back i explained to her that I had just finished cleaning it for myself and she fucking shrugs her shoulders at me and climbs on the machine anyway, smearing her nasty pussy sweat all over the seat. I'm not one to be fucked with so, I very calmly climbed onto the machine next to her, with my friend in between us and continued my conversation with my friend (which was now about how I'm just getting over a nasty stomach bug, throwing up and diarrhea) and I made sure to exhale directly in her face as I explained in detail how sick I was (a lie). The fact that this bitch kept on going, not even so much as a bat of an eye lash infuriated me and I knew it had to be done.....I slowly dragged my middle finger across my forehead, collecting all the sweat and nonchalantly flung it on to the woman, giving her the finger as I did. Of course, I made it seem like an accident but, she knew better. Her face was priceless. She stopped her work out and stormed off, not wiping down the machine afterwards. I immediately called after her, telling her she had to clean the machine. She never looked back. This made me smile and laugh....hard. I know I'm sick but I truly would lose sleep over it if I didn't get her back. Now, whenever I see her at the gym I make sure to make eye contact with her and I always give her a little smile and a wink.
