I’m going to answer this here instead of going off-topic in the other thread, since this one is a watercooler topic, I don’t mind going off topic, and besides, you made it on-topic by making ambivert you word of the day. 
As I have mentioned before, I have a lot of education in Psychology, and a lot of studies are showing that Extrovert/Introvert are not completely static. This includes both over time and between situations. The labels are also criticized because they are not black & white, but are a sort of scale, and not even just a 2D line. In a way, EVERYONE is technically some degree of an ambivert.
For example, a person may be more of one of them at work, and a different degree of the opposite in another situation, such as with their best friends, or extended family, or various other situations. There are a lot of things that affect this. Many people who know me think I am VERY extraverted because in those situations with them, I am. Others, think I am introverted, and in the contexts they often see me, they are also correct. That’s not to say that I am “myself” in one situation and “not” in another. I am myself in both, and happy in both and not faking anything. Things can vary a little depending on my emotions, my degree of comfort, familiarity and many other factors.
This is why I said “somewhat of an introvert” and then added the clarification about what sense I mean…in that I don’t enjoy being around friction/conflict/emotionally volatile situations. They just make me want to leave.
I am also introverted in the sense that I can be perfectly happy staying home most of the time. I do go out and do other stuff for the sake of my family who are not as content that way, but I can be perfectly content and comfortable sitting at home all day every day. Not that I HATE going out and doing other stuff either, but it’s not some big desire like it is for others.
