A lame expression coined by some random guy in 2008, and has apparently been used only by him since then. Egyptians, however, are trying to bring this term back to life currently after being mentioned in a video that went viral on social media, and it's become a linguistic hot potato. Being unable to understand what all the freaking fuss is about, I still don't consider this creepy expression correct, and I don't think it should be used on any possible occasion. Remarkably, many English teachers in Egypt, including sophisticated ones, still claim it is correct!!! Do you have ANY CREDIBLE EVIDENCE?? Come forward.
"My mine" is not a thing! I mean unless u have a real mine lol
