No u: often used by a person who doesn't want to have a social interaction, with a mind that can't elaborate a complete sentence informing the other person that he doesn't want to talk, repeating "no u" for every sentence he hear, annoying every person around him.
Examples:
"Person 1: Do you want to play with me?
Person 2: no u"
"Manager: i'm going to fire you, for list of reasons
Person: no u"
"Person 1: Do you want to play with me?

"Manager: i'm going to fire you, for list of reasons
