What does it mean to go Haymaker on you, am I up against the Amish? That being said I've seen agile fail so hard in so many ways. Currently I'm dealing with incomponent people trying to design and assign tasks.
Means dropping haymakers or swinging his hardest with each punch. No jabs, no uppercuts, just pure power generated from the hatred of the agile stand up meetings. More than likely a fellow Gen Xer who grew up playing punch out and watching Mike Tyson fight.
