My friend said with me:"Hang on to your shorts!" but I couldn't understand this
phrase.Can you explain it?Thanhk

What was the context? Along the lines of "keep your shirt on" as in don't get excited. Or was it weather related? (It's was windy here in Kentucky on Friday. I was almost struck by a shopping cart going 60 mph. But not windy enough to strip the clothes off me.)
