Hi Updog? 

The real meaning behind the acronym HU. Seeing that updog is a very busy guy and not many people get to meet him asking to say hello to him is a big ask.

“HU?”

“Oh my goodness, is Updog really available to say hello?”
“Why else would I ask Hi Updog?”

Hiup 

A combination of Hi and up, no mortal can know what it means

Devine being: what up mortal
mortal: hello my shining beacon of light
Devine being: hiup
Mortal: explodes into nothingness
