Often used to express exclamation about something, or can be used as a greeting or in agreement. But mostly used to as a reason to say something when nothing else can be said; as an ending to the convo or useless part thereof.
As part of a greeting...
"Sudlup dog, sudlup"
As a goodbye on the phone...
"Sweet bro I'll be round later"
Boring convo? Just insert "Sud" and nod your head repeatedly
In a text message...
"Bro come round"
Or can also use "Hud" as word tone is more inflected, thus indicating a question:
"Hud up?" - "Whats up?"
