A lax bro is a guy who plays lacrosse and fully embraces the culture. Commonly found in Maryland, many also spend their time outside laxin' going to Catholic schools and boating. Many lax bros populate Annapolis and the Eastern Shore of Maryland, mostly the Easton area. They spend a lot of time in Ocean City catchin' waves or beach laxin'. Lax bros will often get together for a lax sesh, which usually includes the following: some brews, some bowls, babes, Dispatch, O.A.R., hemp anklets, board shorts, lax jerseys, polos, Madras clothing, Rainbow flip flops, and sometimes Lilly Pulitzer. Many lax bros have long hair and join fraternities in college.
The babes surrounding lax bros are commonly their girlfriends or friends from school. An important thing to remember about lax bros is that they may sleep with a trashy girl, but kick her out immediately afterwards. Lax bros will typically marry the female counterpart to himself, which is a girl who dresses with class and will take their little lax bros to lax practice starting at age 4. These girls also know how to play lax and will lax sesh with the bros from time to time. Many also play field hockey. Lax bros have potential to be assholes to girls and other people outside of their circle, but they are complete gentlemen to their ladies.
Essentially, lax bros are a result of the connotations of beach culture linked with lacrosse culture, the two go hand in hand in places like Maryland.
