Thinking man's/woman's crumpet

Benedict Cumberbatch (left) and Helen Mirren (right) have been described as "thinking woman's crumpet" and "thinking man's crumpet" respectively.

In British English, the thinking man's crumpet or thinking woman's crumpet is a humorous term for a person who is popular with the opposite sex because of their intelligence and their physical attractiveness.[1]

The expression is derived from the slang use of the term "crumpet" to refer to a woman who is regarded as an object of sexual desire.[2]
