Yes, there are several terms that might be used to describe a wife's irrational prejudice against her husband's mustache. Here are a few possibilities:

1. "Mustache phobia" - This term is often used to describe an excessive or irrational fear of something, and could be applied to a wife who has an irrational dislike of her husband's mustache.

2. "Hair hatred" - If the wife has a general dislike of her husband's facial hair, including his mustache, you could describe it as "hair hatred."

3. "Mustache aversion" - This term specifically refers to an aversion or dislike of something, and could be used to describe a wife who has a strong dislike of her husband's mustache.

4. "Beard bias" - If the wife has a prejudice against her husband's beard, including his mustache, you could describe it as "beard bias."

5. "Facial hair phobia" - This term is often used to describe an excessive or irrational fear of something, and could be applied to a wife who has a phobia of her husband's facial hair, including his mustache.

It's worth noting that these terms are not formal psychological diagnoses, but rather colloquialisms that might be used to describe a situation in a humorous or playful way.
