Famous Turkish stereotypical names that have entirely its own meaning just like Karen, Chad etc. in American English
Here are some that came to my mind (I don't necessarily agree with these stereotypes or any of the views they might reflect. The reason of this post is just that this phenomenon really interests me linguistically and sociologically, and also that I thought this could be very interesting and informative for the foreign Turkish learners that don't usually come across these.)
"Kezban" - Trashy, low-class teenage/young-adult girl that usually originally is of Anatolian origin, lives in big cities like Istanbul, Ankara, Izmir etc., conventionally not very "attractive" or "well-groomed", but is still chasing after guys.
(I think this is one of the most famous examples since the usage of it as a given name literally completely fell out of use just because of the stereotypical meaning.
According to nisanyansozluk.com: The meaning originates in 1941 M. Tahsin Berkand novel and later the 1953 film with the same name that tells the love story of Kezban, a young girl from rural Anatolia, coming to Istanbul.
Even though both the movie and the novel reflects only positive traits on the character, the name still came to its completely negative meaning. I think it's possible that the novel/movie first birthed only the "rural young girl recently came to Istanbul" meaning but it then later colloquially shifted to its negative meaning because of the famous prejudice "hillbilly = bad".)
"Berkecan/Berkcan" - Simply the Turkish "Chad". Usually upper-class, teenage guy mostly conventionally "attractive", spoiled, snobby, always partying, always in relationships etc.
(I think this is usage is almost only Late Millennial/Gen Z. I actually don't know its origin but it's very possible that it has connections to late 2000s/early 2010s Turkish web [incisozluk, eksisozluk, Facebook etc.]
Also this is still normal as a given name, i's just associated with youngness.)
Also there is another very similarly natured name and term:
"Meriç" - This name just means guy that always presents himself to women.
(This name originates from a comic strip named "Meriç Olmak" (2008) from the famous caricaturist Umut Sarıkaya.
Literally word-by-word according to the strip itself:
"You are the Young Meriç, the one that hangs around every young girl, the one that girls' boyfriends sometimes bristle at, the one that is annoying; the one that looks like a sneaky but good guy, the one that is the best friend of girls... Go and spread out in the world my lions, fuck those men's lives...")
Eyşan - Morally evil, cheating woman, "wench" (just to remind you, no definitions reflect my views)
(This is a very popular example as well and also pretty much erased its usage as a given name.
This originates from the very famous Turkish TV series "Ezel". It has a character names Eyşan, which is pretty much like the meaning.)
Please feel free to name another examples with the definitions and origins. I would be more than happy!
