I believe this is a form of 'swapping'

One person (Leloo) and another person (Zirzeh) play in a passworded sewer arena TDM. They start at opposite ends; when the round starts, they each throw a 1-hit nade down to the other's spawn - without even trying to not get hit. So they effectively gain a kill each from one another and experience along with it. That round ends, and they do it over and over again.
I'll give each a warning
