A junkie term used to describe when the blood flings out into the syringe from pulling the plunger. This is a way of knowing you hit a vein. The reason it's called 'the flag' is because when the blood comes out it has a flag-waving appearance.
Sally knew she hit a vein when she saw the flag, she carefully pushed on the plunger of the syringe and waited anxiously for the rush.
