English Lesson: I saw you checking out that lady in there.

see (someone)(doing something)

This means to see someone when they're doing something:

I just saw Judy talking to Tom in the hallway.

check (someone) out

To "check (someone) out" means to look at a person's whole body to see how attractive they are. You can check yourself out in a mirror, or check someone else out. You can also "check out" a certain part of a person's body:

Were you checking out my ass?

This is very casual English, of course.

You can also "check out" an object, an e-mail message, a video, and so on:

Check out these shoes I bought. Nice, huh?

But this just means to look at something, and doesn't have a negative sexual meaning.

a lady

"Lady" is another word for "woman".

The word "lady" sometimes sounds more respectful than "woman". You can use it to talk about someone who you don't know:

I met a lady on the bus who said that she was a physical therapist.

It's not very polite to use the word "lady" to directly address someone. It can actually sound rude:

Get out of my way, lady!

"Miss" or "ma'am" are more polite:

Excuse me, miss. I think you dropped something.

But it's OK to call a group of women "Ladies":

Right this way, ladies. Follow me.
