moo 

The greatest word. Ever. Used when there's absolutely nothing else to say, between words, and as a root word. Misled people also believe it's what cow's say, but there's is more like, "MUWOOERRROO."

"...

...
MOO!!"

"Moo. I got a new car today, moo, it's BLUE!! Which ryhmes with MOO!!"

"Mootastic! Mooriffic! Mooness! Mooish! Mooey! Moot! Et cetera."
