The sheer Awesomeness of something that you cannot even comprehend it's Tiddlyfishness.

Something that is so amazing you'll shit bricks!

When you're describing something that is orgasmic.

Awesome, amazing, and fantastic times 10.
"Omg, do you see that freaking awesome, most super, fantastical guy?"

"Yeah, he's totally Tiddlyfish."
