take it easy.

boþver.    (I think)

take it easy

Do you mean like calm down, sakin ol ,but boþver also means take it easy ,I always use boþver like ,forget it

Maybe I am using it wrong

take it easy == iþin kolayina bakmak , aldirmamak

take it easy == sakin ol

personally, if I were to tell someone to ´take it easy´ 

it is usually when someone is going somewhere or leaving or hanging up from a phone call.

so I would say it means the same as ´take care of yourself´  

so, then, eng to tur could be:  ´kendine iyi bak´

 what about "kolay gelsin"?

That means more like ´may it come(go) easily´ said to someone doing a job-may your work go well.

boþver always meant  ´forget it´ where I lived.

It literally means "give it empty"

Forget it!

 In Bodrum/Bitez people say it when leaving friends and even when leaving local shops. You are probably right though.
