I didn't want to upset anyone, I just needed to vent. When you vent, you let something out, whether it's hot air or your feelings. If you express your feelings, you let out a strong emotion and sometimes anger and simply say what you think. Players use Vent as an abbreviation for Ventrilo, a voice and text chat program.
Often, players use Vent to chat with others while playing online multiplayer games. Usually, people vent to their best friend, SO or to someone close who is willing to sympathize with their sad story. It should be noted that Ventrilo does not require a lot of system resources and, therefore, does not slow down players' computers when playing online games that consume a lot of resources. This slang term is derived from the real meaning of the verb to ventilate, which is to allow air (or other substance) get out of a confined space.
In Among Us, impostors and engineers can use a map's ventilation system to move quickly from one place to another. People can also let off steam in private or, in extreme situations, with any unfortunate person nearby.
