An unfortunate snack choice Hey, are you free? Yeah, come over and let's chill. Yo, 'sup, man? Hey, can I have some sweets? Help yourself. Urgh ... I feel sick. Where's the toilet? Right over there. Wait ... these expired three years ago! Slang Free - If someone is 'free', it means they are available to do something. Example: I'm free this Saturday, so let's watch a movie.

'Sup - Short for 'What's up', a greeting equivalent to 'Hi' among English-speakers. Best used with people your age whom you are familiar with. Example: 'Sup, James! How's it going? Help yourself - This means 'Take as many as you want'. It's usually used when talking about food. Example: I've just bought lots of cookies, so help yourself!
