The slang term "vent" means to express strong, pent-up negative emotions—like anger, frustration, or stress—to get them out of your system. It comes from the literal meaning of a vent (letting off steam or pressure). People usually vent to close friends or on social media to feel better "Letting it out": Explaining why youre upset to a friend so you can calm down. "Ranting": Going on an angry or passionate tirade about something that annoyed you. Venting overall is a very healthy way to cope with serious emotions, letting your emotions out rather than bottling them up and then, it explodes like a shaken Coca-cola can spontaneously, Venting is the solution to that. There are two ways you can express yourself when venting, verbally(talking to someone about your feelings in general) and non-verbally(drawing it out if you feel like the feelings are too complicated to talk about). 1. talking about it (VERBALLY): you can express your emotions through talking it out to a trusted family member or friend. 2."vent" art(NON-VERBALLY): if you choose not to express yourself in a verbal way, you can prefer to express your emotions or traumas through a piece of paper, digitally or imagine it in your mind.
