look up any word, like spook:
 
1.
A term of ambiguity that means literally "yes no", also the same as noyeh usually the speaker means No or Yes (but not both); using the term "yehno" in a sentence makes the person being spoken to wait for more words until it can be determined which of the two the speaker meant.
P1: Hey Fred, I see you got a new iphone.
P2: yehno, I just finally decided to clean it.
-OR-
P1: Hey Fred, I see you got a new iphone.
P2: yehno, my contract was up so I got another one.
