* It's a misspelling. Perhaps you meant "whoopee" or "woo-hoo" which are exclamations of excitement or joy.
* It's a slang term or regional expression. Without context, it's impossible to know if this is a specific phrase used in a particular group or location.
* It's a nonsensical phrase. Sometimes people make up words or phrases for fun or to be creative.
To help me understand what you mean, could you provide more context?
For example:
* Where did you hear this phrase?
* What was the situation or topic of conversation?
* Did someone else use this phrase?
With more information, I might be able to figure out what "woo dip harr" means.
