I was watching a movie the other day, and I saw this expression just like that in one of the scenes, the implied meaning was 'for no particular reason'.
The situation was something like this
Guy 1(says) : I am going to X place tomorrow.
Guy 2(asks) : Why?
Guy1 : Just like that.
Since it was some foreign movie with subtitles, so I am not sure if these expression are correct are not.
Is my interpretation of Just like that correct? or Does it have another meaning?
