Re: what kind of hug is this???
apna apna tareeqa hota hay - izhar e mohabbat ka 
Here is an interesting fact, the Inuits do throat singing, it sounds totally creepy (or funny - depending how you look at it 
) , 2 people stand in front of each other, and they blow air from their THROATS into each other’s face 
. This is what keeps them warm during the bitterly cold arctic winters 
P.S.
