To make a "crow of death" basically means to abruptly change the subject of the conversation. The expression is to be used with the finger pointed at something invisible behind the people you're talking to, while saying " the crow of death" using an horrified tone.
Me and my friends were talking about how education is important when Kevin starts talking about how the sky is blue today. He just did a "crow of death".
