When I was growing up I clearly recall one of the three catalogs mom ordered our school clothes from (Sears, Montgomery Ward or JCPenny) called the girls larger size “Chunky” and the boys were “Husky”. I also remember one of them calling the larger girls sizes “Pretty Plus”.
now i want to look up ‘pounds and personality’
UPDATE: I found this and this. An article that says that ‘fatso’ and ‘chubby’ are friendly nicknames? Don’t be alarmed because friends work these things out? and parents shouldn’t help their child because of this? This has been going on far too long. Oi!
