Southern slang

I saw a personalised number plate (licence plate) on a car the other day that said INHGHCTN. In other words, in high cotton. I'd heard this Southern phrase a few times and decided to investigate. Here are some definitions:

• 'In high cotton' is a Southern term expressing the best of times and meaning that all is going very well
• 'in high cotton' - to have a lot of money. Prominently featured in the country-western song "High Cotton" by Alabama . "When we were kids, we thought we were in high cotton if we had a dollar."

There's also a fantastic restaurant in Charleston called High Cotton. When we were there we ate at the sister restaurant Blossom as Lucy was with us and HC looked a little too fancy.
