All tied up

If you're 'all tied up,' it means you're too busy to do whatever the other person is asking you to do. It's a typical expression you hear in an office.

Example:
-Can you go to lunch next Thursday?
-No, sorry. I'll be all tied up in court next week. How about the week after that?

Small-business Saturday

'Small-business Saturday' was started by small businesses in the last 10 years or so to encourage shoppers to support the small 'mom and pop' stores, instead of the giant, big-box chains. It is the day after 'Black Friday.'
