 whats up mate is sedan not speaking? what did you do? are we meeting this week?  you didnt forget your pants did you

my try

Thanks deli!

Just a follow up question...

Does "you didn´t forget your pants did you" imply something else than just forgetting someones pants? Is there supposeably a hidden message or turkish undertone that I don´t quite catch?

...and also...

is "sedan" a name?

Thanks for helping me out. =)

maybe and maybe

I have never seen somebody named Sedan. Sedat, Serdar and Serkan are all real names.

Unfortunately messages like these with abbreviations and slang are harder to translate accurately. 

"Sedan"* is not a name. "Sesin sedan çıkmıyor" is a phrase. It means "you are so quiet" It also means "I haven´t heard from you lately/in a while" .

There is no ´hidden message´ in "pantolonu unutmak". It says, "you didn´t  forget the pants, did you" and that´s all.  

*seda is a girl´s name but sedan (=your seda) isn´t.

Ahhh...ok! Thank you very much for these explanations.

I feel enlightened!

Have a lovely day!

Yours sincerely,

Seda means sound, voice.
