Referring to flow as the elegant "flow" of hair from the back of a lacrosse player's helmet....
Flowseidon is the great god of all that is flow. He governs flow from the crispiest younglings to the highest echelons of overflow. Flowseidon is the final verdict on any young bucks who believe they have achieved flowfection.
1. Trimming or buzzing a bro's holy flow due to certain school, sport, or job requirements.
2. The complete opposite of letting a bro's flow rage.
Brantford Winstonworth: Bro, when I used to play football in high school, the coaches made me get a flowsectomy so I would look like a hard ass. Now I let the flow rage to get the nice lettuce during lax season. It looks so good when I cradle now.
Preston Chadwick: You gotta show me how to get the nice lettuce at the next bro circle.
Flowsiden is the highest a flow bro can be on the scale of flow greatness. If one of your fellow Flow Bros has flow so fresh that there is no other way to describe him other than, flow god, flowsiden is an appropriate name. Flowsiden is a term originated by lax star "Con Bro Chill". Many bros who have flow are either sick at hockey, lax, or both.
"Look at his lettuce, its so flowtastic, i think im going to have a flowgasm, he must be flowsiden"
