This month's lessons are dedicated to the words recently added to the Oxford Dictionary.
Today's word is vom.
It's gross. It's a shortened version of vomit.
Generally, it's used to end a sentence (or is its own one-word sentence) to show displeasure. For example, "And then the weird guy started clipping his toenails on the train! Vom." (Usually, the circumstances are less nauseating.)
Oxford defines the word as an informal verb or noun for vomit.
Don't say it out loud. It's silly.
