Going for a punch while being handed a punch
For example let's say you are person A and person A hits Person B. Person B hits Person A right after Person A sends a punch to Person B, and it's just this repeated process of handing punches right to each other without any sort of defense or hesitation.
We also have blow for blow in a figurative sense, a prank war is a great example of this. As Person A rips a page out of Person B's favorite book, Person B breaks Person A's favorite pencil. It's just a constant battle of retaliation
Guy: Baaabby, can I have a blowblow?
Girl: Aw you're so cute. Of course you can!

BLOW IN
Some one who appears from no where,can be for any particular reason,then is gone,just like that..
Can be used as plural for more than one person ( BLOW iN'S )
This word is not to be associated with the homeless or anyone down on their luck.
All the scum in the Valley blow in one day,cause their shit, and then are gone, like dried dog shit blown away with the wind.
