'Bro'
The Bro Code, we've all heard about it before, such things as 'Bro's before hoes' being commonplace, but what does it actually mean? We hear characters like Barney Stinson from How I Met Your Mother endlessly quote different rules from it. A little research and apparently there are 150 rules contained within his version of it. Mostly concerned with close male friends and there obligations to each other, and in ways that they should aid them in the pursuit of women.
