An insult.

Claiming that someone "got no jams" is basically saying that said person is no fun or anything else along those lines.

It's actual origin is unknown, however it quickly became popular when the rapper and leader of the Korean hip-hop boygroup Bangtan Boys (BTS), Rap Monster (RapMon/Kim Namjoo), turned to one of his members (Jimin) during a flight to L.A and said that he "got no jams"
(Jimin being dumb and a camera whore)

J-Hope: Oh, Jimin is very no fun...

Rap Monster: Jimin, U got no jams.

derives from a korean phrase: "jaemi eobseo" which means no fun or not interesting.
the "jaemi" itself means fun, and "eobseo" can be translated to (there is) no/not.
so basically what you do with it is add "no" in front of the phrase, scratch of the "eobseo" and simplify the pronounciation for "jaemi" into jams

i'm not gonna explain how it's popularized, the result on top of this one can do that just well
