A sexual act almost equivalent to the oral sex act "the blowjob", except for the fact that the person performing the fellatio make a sucking noise, such as a vacuum cleaner would make. Sounds include: "Shhlck", "Slllllluuuuuuupp" , etc.
Fred: Yo man, Daphne and I had the best sex last night!
Shaggy: Like, did she give you a blowjob man?
Fred: Dude, she gave me a freaking reverse vacuum cleaner!
when you suckcoochie as hard as the latest dyson vacuum cleaner. it leaves the person trembling and unable to walk for at least a week depending on how many times you do it.
“omg you did the vacuum cleaner 3000 on me, it was so good but i can’t even sit up”
“as long as it was good i’ll be doing the vacuum cleaner 3000 all the time”
