Esselâmu Aleyküm,

Here is my answer, assuming that you meant to say "the Turkish equivalent of the phrase" by "the opposite word in turkish to the expression".

When we Turkish speakers like someone or something a lot, we commonly use "Maşallah" (pro. "maaşallah"). It´s sometimes used with the belief that saying this word will help protect the admired person or thing against potential evil eyes. I´ve come across people who avoid saying "maşallah" as it is Arabic and/or has religious connotations. Learners can collect many enthusiastic praises by natives just for correctly using that word.

A more secular and less strong version is "Vay" (To make it stronger, say it like "vaay!" or "vaaay!" - the more you admire the more ´a´ you add in the middle.). "Vay be" is also used (Say it like "vay bee" or "vaay bee".

"Wow" is also used in Turkish conversations among some Turkish speakers who speak English. They may be told off or scorned for saying "wow" by some native speakers of Turkish, but you will more likely to get away with that if you are a learner of Turkish.

"Oha" (Say it like "oohaa") is a popular slang word that is used as a reaction to something big, unusual, very good, beautiful, very expensive, unacceptable etc.

Rica ederim.

"vay" is fine.

"vay anam vay" is better as it´s more colloquial and funnier. It would look extra cool if it gets out of learners´ mouths!
