the act of imposing a distorted reality which entitles you to something otherwise not deserved;

what your girlfriend thinks your constantly doing.

An art that is very hard to master and dangerous to fail at.

There is a great many things that are considered lying. If someone tells you something false, knowing it is false, they are lying to you. If someone breaks a promise they made to you, they lied to you when they made the promise. If someone tells the truth, but leaves important details out, they are still lying. If someone (say you're in a relationship) is going behind your back, about important things (going to girls/boys houses without informing you) that is withholding important information, which is lying!!!

The ability to use the least amount of information (from the given truth), bend it to your will, add some bullshit to it, and add a dash of charm/reality-distortion field, while slowly changing the topic

a master degree in communication sciences only for women, while men can't lie.
