It's a juicy answer!

80% of office gossip is true?!

Whoa.

I do like that what you say about others reflects yourself:

When you gossip about another person, listeners unconsciously associate you with the characteristics you are describing, ultimately leading to those characteristics’ being “transferred” to you. So, say positive and pleasant things about friends and colleagues, and you are seen as a nice person. In contrast, constantly complain about their failings, and people will unconsciously apply the negative traits and incompetence to you.

What you say, comes back to you.
