that's it

They can call their parents, the police, and that's it.

Here the phrase that's it means nothing else. We use the phrase that's it to show that no more information is coming. Notice the following:

1. The hotel is so basic. You get a bed, a chair and that's it.
2. I will lend you some money, but that's it. Do not ask again.

racking up

To rack something up means to add something up. You can rack up a bill, or rack up a debt. It just means you keep adding to a total. It is not only for money. For example, you can rack up points in a video game. Notice the following:

1. He racked up a big debt in college.
2. She racked up many frequent flyer miles with her travels.

massive bill

When you have a massive bill, it just means a very large bill. You can also pay a massive fine, a massive amount, and a massive charge. Notice the following:

1. He got a massive bill for his home repairs.
2. He had to pay a massive fine for speeding in his car.

glued to

They are glued to their cellphones.

Glue is a sticky substance that holds things together, so when you are glued to something you appear to be stuck to it. People can be glued to the computer, the TV, or a book or phone. Notice the following:

1. He is always glued to the TV watching football.
2. She is glued to her phone. She is always checking it.

anti-social

It seems anti-social to me.

When people are anti-social, they are not very talkative and tend to not socialize with other people. People can seem anti-social if they are quiet or avoid interaction with people. Notice the following:

1. He is very anti-social in the office. He does not talk to anyone.
2. Computers can be anti-social, but they can also bring people together.
