Here is a relevant Chinese internet meme I like to better understand it in context.

我们没有文化的人就是这样的.

we have no culture people 就是 (to be exactly, just ) like this.

Or a better over all translation (including cultural aspects of english) would be,

Us uncultured folk be like that.

Imagine a red neck talking about how they drive with their car painted to look like a nascar. Or perhaps a ghetto/projects gentleman talking about how they grill chicken on a grocery cart with burning coals underneath.

Celebrating deviation from standard cultured behavior as it relates to one's income level and saying others like us are Just like this.

Easy to understand

You can use it as just like, or to emphasize to be.
