I´m trying to work out if my friend has sent me the wrong message here that should maybe be for someone else, but he writes with lots of slang and I can´t always understand . Can someone help translate for me? Tesekkür ederim.

gercı zehra baskalarına da çakabilirsin dio..geniş kız ‎

So, I try, but wait for a native speacker to tell if i´m right for all the text.

gercı zehra baskalarına da çakabilirsin dio..geniş kız  => it´s true, zehra says that you can "go with some others people" (I think I know what çakabilirsin means but... I can´t translate it).

Genis kiz : I don´t know if I´m right but I think it´s an expression to say that it´s a girl who doesn´t have honour.

jnq are you sûre ?

because if he said "dont stay" it would be "kalma"

here it´s "kalmaSIN" ... Doesn´t it for the third person ? 

I think you´re right Emine

kalmasın - don´t let him/her stay

kalma - don´t stay

You are right Emine, totally overlooked that. I adjusted it.

I don´t think that you know. Sorry, I don´t think it is appropriate to translate so easily, but simply it is about having sex with a girl

Yes i know it but it´s too vulgare to translate it 

Thank you all for you help. I´ve learnt something new today!! Also shows me that this message was not meant to be sent to me - clearly a conversation with his male friends!
