너무 싫어요.

The word '너무' (neomu) means 'too much' or 'excessively' and '싫어요' (sireoyo) is the polite form of '싫다' (silta), meaning 'to dislike' or 'to hate'. The combination emphasizes a strong feeling of dislike. While '너무' historically had a negative connotation, it is now commonly used to intensify both positive and negative feelings. In this context, it expresses an emphatic statement of strong dislike or aversion.
