The phrase "that would be what we call" is an idiomatic expression used to introduce a common name, term, or description for a particular situation, concept, or object. It is often used to clarify or define something for an audience, often with an emphasis on the typical or generally accepted nomenclature. 

• Introducing a common term: "A 'dummy' is the British term for what we would call a pacifier".
• Describing a situation: "This is what we would call a core recognition".
• Highlighting a typical experience: "At the age of 40, he had what we would call a peak experience".

A "dummy" is the British term for what we would call a pacifier or soother. -
