look up any word, like darude - sandstorm:
 
1.
this is redneck slang for the word yes, as in the person understands what you are trying to say and replies with this word to show you that they get what you're saying
"Do you understand what I'm telling you?"
"yauhn!"
"I like to build robots, what about you?"
"yauhn!"
