Similar to drive-bys. However in this case the act is to satisfy an acquaintance by driving by in a 20-inch rimmed car, dropping a 'ho' out and allowing him to suck the acquaintance's cock.

Blow By
The jizz that runs out of your chicks mouth and down her chin after a huff because it to much to swallow.
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
