I always knew these types of buns were made using a donut foam. Still never stopped me from popping a massive stuffy, everytime I saw one

These buns used to be super popular, among girls in my highschool. As a result, I got to see one of the girls re-doing her bun, and saw it was made using a donut. At one point, almost every girl in my highschool would be walking around with these nice round buns on their heads, and a lot of the buns were HUGE. Made me develop a fetish for sock buns, which was helped by the fact that I already had a long hair fetish to begin with
