FACEBOOK/ POSTING/Mentioning Ronda Rousey?

[Xave]

Im a fan of Ronda Rousey and I liked her Facebook page. After liking the page, several days after while i was online, A post pop out of my Timeline, when I looked at it to see who posted it, it was someone I didnt know. She wanst my friend or anything like that, the only thing that we have in common is that we both liked ROnda Rousey's page.

In her post, she mentioned Ronda Rousey once. My question is, how did that post appearded on my timeline???????? Cause I tried posting something, mentioning a page and a friend of mine also liked that page that I mentioned, so I asked him to check if my post will appear on his timeline, since we both liked that page, but It didnt.. We're friends and my post about a page we both liked didnt appear on his timeline, while a total Stranger, mentioned a page that I liked (Ronda Rousey) and it appeared on my timeline....

Can somebody please tell me how it works cause it's driving me f#cking nuts!!!!!!! Thanks in advance.. peace..
