A person whos hair 'flows' out of the back of lacrosse helmets. This essential piece of hair can also be referred to as 'lettuce.' There is a very fine line between great flow and over flow. This great flow is commonly called 'flowfection.' When the flow is totally out of control it is called a 'flowtastrophe,' but that is not here nor there. For more information please refer to the youtube video "The Ultimate Lax Bro."
Lax bro #1: That guy has great lacrosse flow!
Lax bro #2: Yeah, too bad he has no helmet tilt.
