What is Nighthawking?
1.
The act of two men meeting up, having a vicious fight - then giving each other one up the plopper.
Jack was covered in bruises and walking like John Wayne... He'd been nighthawking again.
2.
The act of shooting someone from a far distance without anyone noticing.
I was nighthawking in Counter-Strike when someone walked up be hind me and shived me in the skull.
