What does selling optical communication equipment mean
Merriam-Webster defines it as a “humorous internet slang term” meaning “to outclass,” typically used to describe someone as far more attractive than another. Six seven is mostly a nonsense reference used by teens. However, it does have some meaning depending on how it is used. Saying 67 with that hand gesture can mean “so-so” or “about”, but the emote can. According to Newsweek, a record high percentage of Republicans from across the country now identify as part of President Donald Trump's Make America Great Again movement, with about two thirds defining themselves this way. Erika Kirk, wife of Charlie Kirk, made her first public address on September 12, just two days after the conservative political activist was shot. At its core, “mogging” is about comparison: when one person significantly outshines another in looks, physique, or even life status.
