The sound made by a deadly Tennessee tornado.

It may last a decasecond.
It may be followed by screams from a man.
It may be the worst sound one has ever heard.
"The worst sound Eric Funkhouser said he has ever heard was a 10-second 'voom' followed by a man's screams."

Like mooned except it's a vagina that's being shown, not a butt.
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.

It's like mooning, but with a woman's vagina.
On the way to the Keyport hardware store Mark drove past the women's penitentiary and he sure did get a show! There were women hanging out their junk vooming him and yelling, "Hey bok-man check me out... Voom, voom, voom me!"
