(someone) claims to (do/be something)

Use "claim to ___" when you want to tell what a person said, but you also want to suggest that you don't believe them, or don't know if what they said is true. For example:

I once knew a guy who claimed to be able to remember every telephone number he'd ever called.

There are two different patterns that people use "claim" in. One is "claim that ___", and the other is "claim to ___":

They claimed to be police officers, so I let them in.

They claimed that they were police officers, so I let them in.

(someone) is a hypocrite

A "hypocrite" is someone who loudly pretends to be good, but secretly does bad things. Or someone who does the same bad things that they criticize others for.

For example, a preacher who teaches his congregation not to chase after money, but actually lives in an expensive house and drives a luxury car himself, is a hypocrite.

Another example is a parent who tells her teenage daughter not to smoke, but is secretly a smoker herself.

Politicians, religious leaders, parents, and teachers are often accused of being hypocrites.

(someone) is all about (something)

You can describe a philosophy that someone often talks about and emphasizes this way:

Mom and Dad were all about me going to college and studying medicine, even when I was just a little girl.

The marines are all about respect and loyalty.

You can also use "all about ___" to talk about something that you're strongly interested in, or something that you concentrate on:

These days, I'm all about cutting loose and enjoying myself.
