For example; someone I work with always has a bigger thing. She's about 50-ish but whatever you have... hers is bigger.
People talk about their house and she'll ask you what size your back yard is and even if you say 5 acres, she'll tell you that her house in a built-up area is much bigger. If you've got a garage, she'll ask how many cars you have - if you say two, then she will tell you that she has four - and that they're Mercs, Jags etc...
Her children are the "best" in the school and they do everything they're told but are very independent too.
Whatever movie you just watched she's either seen it twice or it's rubbish.
If you've just met someone important for a business discussion, then that's ok because her cousin is his boss.
I generally ignore her and let her ramble on but she's irritating a lot of people at the office. As a general rule you can't believe ANYTHING she says.
That's a bullshitter. Someone who compulsively lies about things that don't need to be lied about.
