You are probably refering to the handkerchief code, also know as flagging. This system utilizies handkerchiefs to indicate sexual preferences and availability. It was popular among gay men of the 1970s; today the code has been adopted by members of the BDSM community as well.

-Sexual practices of interest are indicated by colors.

-Whether an individual is a "top" or "bottom" can be determined by which pocket the hanky is placed in.

It depends on what color scarf & which pocket. I was a f** hag in my youth & the bar I went to would pass out a card explaining what they meant. Ask the bartender.

It depends what colour it is and which pocket...it sounds like the 'Hankie code' that was used in clubs to denote what each person liked to do in bed...

Thank you for that interesting question and answers. Didn't even realise there was something out there being used. Now I know.

He's expecting a cold spell and his pockets are nearly full.

its not somthing thats used much nowdays, it tells what your into / looking for.. im not sure what the colours mean but i know red means fisting (ouch)

means he needs bigger pockets

It means that he is available and looking.
