Timing is everything with this word. It's impolite to use it in the middle of a conversation, because its intended use is for when you meet up with someone who knows what the word means in the hallway of a schol, run into them on the street, bumb into them at a party, ect.
It can also be used if you are trying to get somebodys attention when there are plural people in the same room with the same name as your friend.
"hey, i dont feel like having a serious converation, whats up"
"ya, im in a good mood, id rather joke around than have serious discourse"
"i would like to have non-serious discourse"
