The third week of April on a Saturday, when you and what you consider to be one of your best friends spend the entire day together doing the most exciting things. This may involve leaving a shitty town to go to a large one and fuck bitches and get money. Or just having a super fun day shopping, eating and fucking around and always be laughing.
Levi- "Dude are you ready for a fucking badass Broski Day!?"
Ricky- "Well of course! I set some bitches up for the end to make our Broski Day complete!"
