falan is a strange word. In which context is it commonly used? Please give some examples

Falan is arabic, in arabic we use it when we dont wanan say a persons name , or were giving an example  of something like falan we falan (a person and a person)

or falan told me that.......

or it could take the emaning of such and such etc etc

but i dont know how they use it in turkish...

We use that mean as well.

And also it used as "et cetera" informally.

Hmmm so you say like i want this this and faln falan?

U know we actually pronounce it mor like fulan than falan but its really close

 For example we say, kitap falan aldým..

And also, it can be used combined with filan, as falan filan, and you can use it like blah blah:

Sonra konuþtuk falan filan, ve iþi tatlýya baðladýk.

falan
pronoun (arabic origin)

falanca
sýfat (adjective)

falan filan
noun

Falan...falan filan, vesaire vesaire, þey...ve....veya (ya da) ...belki...ama...þu ya da bu..., o ya da bu..., öyle ya da böyle..., þöyle ya da böyle..., yani..., bu demektir ki...öyle bir þey ki...diyeceðim þu ki..., oysa ki...,kaldý ki...laf olsun diye..., iyi de..., öyle olsun..., ha demiþ ha dememiþ..., ha olmuþ ha olmamýþ...vb.
