A word that is used by french canadians meaning that they sneezed. It is still quite controversial if it's an actual word or just a slang. The ER at the end, is the ending of a verb and the atchoum the the noise that a person would make if they sneezed. People usually say that french is a sexy language and that by throwing some french in random sentences, it becomes sexier, so no worries... If you say atchoumer, all them sugar babies will be throwing themselves at you thinking that you are a rich ass french sexy man, when in reality you're just an average middle aged man from alabama that read this definition.
