I have seen food vendors advertise barbe à papa and it did not take too long to figure out what it was.
Barbe à papa directly translated means dad’s beard. The same product is known as cotton candy in the US.
I don’t think cotton candy has much resemblance to any father’s beard I have ever seen.
From an eating view point, anything to do with a beard sounds quite unattractive and uneatable.
From the opposite view point, I cannot imagine something as soft and sticky as cotton candy on my face.
