"Oğlusuma Harbiye´de bayıla bayıla yediğim sini oruğu ve düğün çorbası yaptım."

What is oğlusum? Looks like two different possessive suffixes in one word. Is it some kind of a term of endearment?

oğlum: my son

oğluşum: my little and pretty son!

"oğluşum" does not seem grammatically correct. In order to show love or to express funny things, sometimes we bend the grammar rules. I think it imitates the following correct suffix but it can be added to verbs only, not nouns. "git-me-m / gid-iş-im"

another theory, from the word of "minnoş" when we say "mini" or "minik" it means small and most probably cute. if we want to add more cuteness and love we jump to the word "minnoş" so the Mom there tries to express all these meaning in her Son, even if it is grammatically wrong.

it is something like kediş ( a kitty) or köpüş ( a doggy)

Never heard the word KEDİŞ or KÖPÜŞ used in Turkish before.

Mini and minik both mean small/tiny....minnoş refers to small kitten. (you cant have a minnoş car)

I have heard 3 weeks ago at TRT Çocuk - at Pepee dizisi; and I watched it every day for 1 week..so...

What was the exact time ?

Afriend of mine here claims KÖPÜŞ is the name given to baby KANGAL dogs.

I dont want to argue with you..never..you are a native and you know better

all I want to say is in the series I have watched the little Pepee called his dog with köpüş and his cat - kediş

Thank you all. So it is another diminutive suffix  -  and lack of dotted letters in the text led me astray.
