Usually a member of the Juggalo/Psychopathic family will use this as a welcome, calling "whoop whoop" to another Juggalo/lette.

WhoopWhoop is the middle of no where.
An unknown town that no one has ever heard it.
The population is so low that everyone is related to each other in some way.

The sounds of the faggotry that is ICP. Juggalo's Juggalette's and all other JuggaPussy's seem to convey this message to mean What's Up. But in reality it's dumb and makes you want to punch them in the fucking throat. They say it to sound cool when talking to their friends because other than saying that and drinking Faygo, they have no life. Faygo for the Faygo's.

when a juggalo wants his ass whooped he/she what ever the fuck it is, will scream Whoop Whoop!
