تظاهر به ناراحتي و درد و زجر كشيدن

It means to do something or behave the way that others feel sorry for you :)

try to show that somebody is bored but it was not real.

it kinda means something like making a lame excuse.

The idiom ننه من غریبم بازی در آوردن almost has the following connotations: -to keep whining and protesting over a small problem and try to make it seem like a big injustice; -to always try to make oneself seem like a victim of oppression in a loud/exaggerated/dramatic manner; -to try to gain the pity of other people for every small problem that happens to you;
