ELI5: What *Exactly* is Money Laundering?

Libor has me completely confused. I understand money laundering involves illicitly attained funds. But that's it. When people say banks /businesses are involved in money laundering what does that mean? How? What are they doing? And how is a bank supposed to know a legit deposit from one that is "laundering"? And how would they launder money for a country? Do they just say, "Hey, I'm a controversial Middle Eastern Country, and I would like to open an account?" And what good would that do anyway? Sorry for the question overload.
**TL/DR: I know nothing.**

Bully steals 100$ from a kid but he cant just spend it because his mom will be suspicious of where he got it. So the bully asks his friend to come to his house and offers him 100$ in front of his mom for some lame toy. 

Now mom thinks this retarded kid just gave her son 100$ for a worthless toy and is not suspicious of where the money came from anymore.

Bully gives his friend 10$ for the favor and everybody is happy. Well except for the poor sap that had 100 bucks stolen from him.
