This phrase usually means "that's sexy" although it can also mean "that's cool."

In 2005, celebrity Paris Hilton began using "that's hot" as a catch phrase, increasing the popularity of the less common "that's cool" meaning.
The more traditional "sexy" meaning:
Chad: Check out my new miniskirt.
Derek: That's hot!

The recently popularized meaning:
Chad: Check out the celebrity phone numbers I downloaded from some the net. Some stupid famous chick had them on her mobile phone and they got stolen.
Paris: That's hot!

Some dumb bitch Paris Hilton with NO brains COPYRIGHTED this phrase. So now I can't even say it, nor can you, for if you do, she get's paid. That's not hot. Also, she said herself that she has no talent or personality, yet she's famous worldwide. I agree with that goddamn bitch.
You: That's hot.

Me: Great. Fucking great. That bitch just earned about 35 million because of you. I hope she spends it on food, cause that is what she needs to have more of. Anarexic whore.

The phrase used by Paris Hilton to describe global warming. Paris is going to stop playing the dumb blonde and watch "The inconvienent truth" on dvd and then have a serious talk with her father to meet with Al Gore to make sure the Hilton Holtes have a major part in saving our world. This will redeem her unsavory past and give her some substance. NOW THAT'S COOL!
"That's hot, and it's getting hotter"

Don't wait, to take action, this is not the diet that you will start tomorrow, we have to act NOW !

Our future depends on it...
