Like a Coomer, but for cars. A person who likes cars too much and says shit like "Oh yeah that's a V8 Super, it has 230 Horsepower" when no one really asked. Always puts cars on his story.
Vroomer: "Oh yeah that's a V8 Super, it has 230 Horsepower"
Me: "Did I ask"
Vroomer: "Dude how do you not know G8 SuperX from Honda"
Me: "Okay Vroomer"
I barged into my sister's room because she stole my headphones and she had just gotten out of the shower and had no towel on. She turned around and voomed me after she mooned me with her butt.
