Since that to call "mine" is not permitted in soccer, one must name the player to recieve the ball. When one forgets one's own name (often happening to a goalie who has had one too many kicks to the head) yelling "Brendon's Ball!" is the same as claiming it for yourself. The "Brendon" was originally Brendon McCullum, wicketkeeper for the New Zealand Black Caps.
"Defence, defence, mark up, she's taking a shot!"
"Shit, never mind, mi- oh, Brendon's Ball!"
