Jams on Toast 

Basically anything brilliant. Especially if it's to do with trampolines, fruit and vegetables, tents, or fun in general.
The s was added onto the end of jam in honour of the comedy legend Jim Jams.

"Hey, how was your little camping trip in your boss' garden?"
"Jams on Toast"

You got no jams 

You are no fun

The origin of this phrase "you got no jams" comes from korean word "재미 (jaemi)" which means "fun". Jaemi and jams sound familiar, so Rap Monster put jams instead of Jaemi in the sentence making it funnier.

P.S : In korean, "you got no jams" is "너 재미없어 (neo jaemi obseo)"

J-hope: Oh, Jimin is very no fun
Rap monster: Jimin, you got no jams

Boner Jams 

a reference to 2005 American comedy film The 40 Year Old Virgin where Paul Rudd's character, David gives Steve Carell, Andy a box of the best pornos called "Boner Jams". Boner Jams is a list of the best videos that busted your nut! aka ejaculate. Wankers keep a list of videos that made their cock explode baby batter.

Wow this video of a slut getting plowed up her cunt and ass made me Bust my load! I'm adding it to the "Boner Jams 2022" playlist!

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
done~

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

Rap Monster: Jimin, u got no jams
