How do you say “Random” in Farsi?  I look up and find:

تصادفى، اتفاقى، بى نقشه، بدون ترتيب

بدون ترتيب is more like “non-sequitor”, right?

Which one of the others captures “random” the best? 

I like to say “that was random” a lot. Or just, when something weird happens, like when YOU walk by, an exclamation of “random” would be appropriate.
