What is the meaning of 〜たりして?

Question

I've just come across "〜していたりして" at the end of a sentence in a post on Facebook, so it's probably very casual. Does anyone know the correct meaning and typical usage?

Answer 1

たりして is used to posit some event as a possibility but something you are not sure about. For example, about the future:

10年後に大金持ちになっていたりして。

From the nature of this expression meaning "not being sure", it is also used as a hedge when you want to be modest and a bit comical:

ひょっとして、さっきのことでまだ怒ってたりして。

Answer 2

I'm not sure what part you're stuck on, and we can give more relevant answers most of the time if we know the context, but here we go:

している is the present-continuous short form of the verb する (to do).

The 〜たり suffix indicates an incomplete list of one or more actions (more on that here), for example

新聞を読んだり、コーヒーを飲んだりする
Read a newspaper, drink coffee, and so on. (or)
Do such things as read a newspaper and drink coffee.

So the best translation I can give without the context here is:

〜していたりして
Doing such things as ~

As for why the final する is in て-form, that would be easier to answer if we could see the full sentence.
