It has two meanings.
The first is “be called“ and it is used to say what someone/something is called.
The second is “it means/that“ and it is used to emphasize what you mention before “という(言う)“ . It is often used to describe the meaning of something, to tell the point of something, or to tell what you hear/read. “っていう“ has the same meaning and it sounds more casual.
Meg is talking about the person in charge of accounting.
- Meg: I’d like to file an expense report, but I don’t know what to do first. Do you know about it?
経費を申請したいんだけど、まずどうしたらいいんだろう。知っている？ - Amy:Yes, you can call a man named Kim in the accounting department. He will instruct you on how to submit the report.
うん、経理部のキムさんという人に電話すればいいんだよ。申請書の提出方法を教えてくれるよ。 - Meg: Thanks! (A few minutes later after she called him.) It went straight to voicemail and it said that he was on a business trip and would go back here in 3 days.
ありがとう！留守電に繋がって、(キムさんは)出張中で、三日後に戻るみたい。 - Amy: Which means you may not submit the expenses this month, right?
今月、経費を申請できないかもしれないっていう事？ - Meg: Yes. I’m okay if I get reimbursement for it next month.
うん。来月(経費を)払い戻せればいいよ。

Ken and Leo are talking about girls.
- Ken: Sara often uses hearts in the text (messages). Does it mean she likes me?
サラは、チャットでよくハートを使うんだよね。それって、俺の事を好きっていう意味かな？ - Leo: I don’t know how she feels about you. Girls tend to use a heart icon so often.
彼女の気持ちは分からないけど、女子って(ハートを)よく使うよね。 - Ken: Huh, I don’t like girls who are a teaser. I almost fell for her.
あー、思わせぶりな女子は嫌だな。危うく、引っかかるところだった。
