SNOWBIRDS are the people that immidiately flock to anyone that is in the act of using or preparing to use cocaine.
People that gather around you while in the act of using or preparing to use cocaine. They try and act friendly or as if they are your friend. When really are only acting selfishly, hoping to score a free line.
Man 1-Hey man would you wanna sniff a line?
Man 2- Hell yea!... But hey there's a lot of people, watch out for snowbirds!
