Pee-pee, wee-wee, childish term for genitalia. The standard, polite term parents use with toddlers to talk about anatomy, hygiene, or using the potty (надо помыть писю и ложиться спать — “you need to wash your wee-wee and go to bed”).
Пися у неё красивая, как розочка.
Her wee-wee is beautiful like a rose.
