When you want to be hip so you ask your friend,
whats up dog. If your friend is being a
complete idiot or you don't have any friends you can
go with a simple joke such as an example written below
You: Yo
whats up dog
Friend: Nothin man just chilling
If you want someone to say what ups dog
You(point at a random object): Wait, I think
that's up dog
Friend:
What's up dog?
You: Not much man, what about you
