A form of blindshot involving two attackers working in concert against a single unsuspecting opponent. The first attacker will point behind the victim and loudly exclaim "look out behind you!". The victim will generally ignore this as an obvious attempt to gain an advantage via deception, at which point the second attacker hits the victim from behind. This term comes from the New Zealand animated series Bro' town
Vale: "Look out behind you!"
Victim: "Ha ha, foolish child, I'm not falling for such a ...."
Valea: "Yeah, Morningside blindshot!"
