I don’t understand the meaning of “冗談 通じんじゃん” in below sentence


The whole sentence is: “笑える! コタってつまんない男だと思ってたけど案外 冗談 通じんじゃん。” I checked on the
internet and found “冗談が通じる” which means He or she gets the joke. But in the
sentence “冗談 通じんじゃん”. the word “じゃん” is the colloquial contraction of “じゃない”
and sometimes it means “actually”. I‘m confused what is the exact meaning of
“冗談 通じんじゃん”. whether it means “Kotaro does not get the joke” or “Kotaro gets
the joke” by the way, the space between 冗談 and 通じんじゃん is the same as in
conversation.




As you pointed out じゃん is colloquial contraction of じゃない and here I would say
that it's more in line with meaning "right?" or seeking some kind of
confirmation from somewhere in English.

Since you mentioned it, I also wouldn't focus too hard on the space between 冗談
and 通じん. I understand you found "冗談が通じる", but I wouldn't say there is a space
because there is no が or something like that. The が is just being dropped /
omitted because the casualness of the conversation. This space is more of just
a pacing or pausing effect for the reader more than any other significant
meaning from my standpoint.

So "案外 冗談 通じんじゃん" seems to mean "surprisingly they got the joke, right?"

With the whole sentence and assume it's directed towards Kota, we get
something like:

> 笑える! コタってつまんない男だと思ってたけど案外 冗談 通じんじゃん。
>
> They can laugh! I was thinking Kota is a boring guy but surprisingly they
> got the joke, right?
