In this version of Equestria from the show My Little Pony Friendship is Magic pee culture plays a large and significant role in the day to day life of the ponies that inhabit the land. No matter the age, gender or occupation pee maintains a prominent role to ponies in forms of acts like drinking, holding, public wetting and more. Even public events and ceremonies have important sway with pee culture. Spells about urine all plenty about too.
