3-0 

When you win and completely obliterate someone or something unanimously. This comes from rap battles that have 3 rounds and if someone wins all 3 rounds, the loser was 3-0d. This can be pronounced as "three-O" (the letter o) or it can be pronounced as "thirtied". Some people say three zip.

I just took a Microsoft exam. I 3-0d it.

I just raced Mike down the road and 3-0d him.

3.0 

Verb, meaning to completely dominate something. Comes from the card game Bridge, where the best strategy that ever was is named Bitchkilla 3.0.
The full name of the strategy, however, is inappropriate in mixed company, therefore, the term '3.0' was born.
Same as pwned.

"Dude, you just got 3.0'd!"
or "Ok, time to 3.0 these suckers."
