A kugel is a special breed of rich middle-aged woman living in Johannesburg. Originally, the word kugel only applied to Jewish women (a kugel a Jewish potato-based dish), but now applies to any spoilt housewife.
Very distinctive characteristics of kugels are: A very nasal accent, calling everyone "doll", looking down on people who don't live in the Northern Suburbs, mistreating their housekeepers, spending half their lives talking on a cellphone, intense Botox treatment, wearing leopardskin patterned clothes and driving fancy 4x4s but refusing to take them offroad.
They tend to congregate at Sandton City, talk about shoes, nails and other kugels, cheat on their husbands and only tip 5%. A classic stereotypical kugel is Gwen Anderson from the South African comic strip Madam and Eve.
Kugel: Like, you know what I'm saying doll, she knows her husbands having an affair with....(25 minutes pass)... anyway, I have to like hang up doll, my nails are almost dry and I have to hurry up to get my hair done... ok doll, mwah bye.
