The phrase "down up" is not commonly used in written English and may not be considered grammatically correct.
It is usually used in spoken English as an informal expression. However, it can be used in written English in specific contexts such as informal or creative writing. For example, in a dialogue between two friends, one could say: Friend 1: "Hey, do you want to go down up the hill and watch the sunset?" Friend 2: "Sure, that sounds like a great idea." In this example, "down up" is used as a phrasal verb and means to go up or climb the hill in order to come back down and watch the sunset.
