The word 'gaga' (crazy) clearly belongs to colloquial language. It is rarely used in formal or written contexts.

'Gaga' (crazy) is almost always used predicatively, that is, with verbs like 'sein' (to be), 'werden' (to become), or 'machen' (to make). Using it directly before a noun (attributively) is very rare and sounds unnatural.

normal
'normal' and 'gaga' can be used as opposites when talking about behavior or thoughts. 'normal' means that something is usual, understandable, or expected. 'gaga' is colloquial and means roughly crazy or not quite right in the head. The word sounds casual, but it can also be disrespectful, especially when talking about people. In factual situations, 'ungewöhnlich' (unusual) or 'seltsam' (strange) is often better than 'gaga'.
