What does "thirteen" mean here?

I can't tell you what it is supposed to mean, because i've not seen the movie. However, saying thirteen is two words is a rather lame, and overworked joke. People who aren't very bright have commonly said something to the effect of "I've got just one word for you," and then they say more than one word. So this kind of thing is a sort of inside joke, understandable to speakers of the American language. But it's a worn out joke, and as is so often the case, the screen writers in Hollywood haven't gotten the memo yet.

thirteen might be the spy's number.
think "007"...

How about bad luck, or jinx...

NO, NO. 13 is not his number. In that film, every spy has a code name such as firefly, rather than numbers.
Does thirteen mean supid here? I am not sure.

No, thirteen does not mean stupid.

In China, especially the city of Shanghai, 13 o'clock means stupid, silly.
I don't know whether it has the same inplied meaning in the English-speaking countires.

No, it is not so implied in English. In fact, military time notation refers to 1:00 p.m. as 1300, and many European countries use such a system to avoid confusion between 1:00 a.m. and 1:00 p.m.

When Pamela Anderson married Kid Rock, a reporter asked her how she got through the multiple wedding ceremonies and heavy partying.

She replied, "Two words: champagne."

Is it Jackie Chan saying the line?

I suppose it's supposed to be funny because he doesn't speak perfect English.

Yes, thirteen was said by Jackie Chan from China. Therefore I think may be thirteen has the implied meaning of Chinese, silly or stupid. If you say 13 O'clock in Chinese, it means u thinks someone is silly.

The point has been made that on a 24 hour clock, 13:00 is not silly.

We cannot answer the question
without having the context from the movie itself.

I have not seen it.

Thirteen would still be one word, though. I don't think your explanation makes sense, given that the writing credits are Jonathan Bernstein, James Greer, and Gregory Poirier.

Ian：It doesn't look like they have chicken tenders here.
Bob: Wait inside. I have to make a call.
Firefly: This is Firefly.
Bob: This is Bob Ho. I need help.
Larry: Yeah, so I get pretty good grades at this university. I'm top of the class. I don't like to brag, but, you know.
Farren: Bob, this is Larry.
Larry: Pleased to meet you, sir.
Bob: Let's get some food.
Farren: He goes to the university.
Ian: He's a poet. Isn't it cool?
Bob: It's rad. It's awesome. It's jiggy for shizzy. It's the bomb. Let's go.
Farren: Hey! How embarrassing.
Ian: You know, most people don't like me when they first meet me. But Larry did.
Bob: I have two words for you, Larry. Thirteen.
The above is the lines.

That looks like something that came out of Mad Libs.

It means the perfect joke to add to my repertoire, silly.

Is 14 funnier ????????

Thirteen doesn't refer to some Chinese thing. Bob is referring to feren's age by saying thirteen and asking Larry to stay away from her.
