A family reunion involving a pool, a barbecue, sports and genuine fun in the sun!
Cool Bro: Dude are you going to Amy's party?
Cousin: No way dude, I get to go to a Splash Bash!
Cool Bro: You're so lucky, I wish my family loved each other enough to throw a splash bash... but they don't.
Cousin: Oooh... awkward.
