Newton Central School's principal Riki Teteina used the term to describe cyclists who had verbally abused or almost collided with parents and children on their way to school along the congested shared path.
The school cancelled its walking bus this year because it was too dangerous.
Auckland Transport's network management and safety manager, Randhir Karma, said Auckland Transport staff would hold a pit-stop clinic next week near the busy section at the city end of the cycleway.
It would try to educate the cyclists as well as scooter riders and walkers, he said.
Staff would provide parents with high vis vests and accompany them and their children on their walk to school, he said.
It would also repaint the cycleway's centre line.
But Mr Teteina said a painted line didn't cut it.
The only meaningful safety improvement would be Auckland Transport widening the congested piece of cycleway, he said.
He was frustrated that none of AT's bosses had fronted up to the school.
"Those who make the decisions are the ones who really need to get in touch with me. Stop hiding behind middle management and explain what they plan to do and what their timeline is going to be," he said.
Auckland Transport said the widening issue was complicated because a number of different land owners were involved.
It needed to sort out what land was needed before it could look at any engineering work, he said.
Mr Teteina said the community was behind his stance, with more parents had coming forward since RNZ's first story with more tales of near misses or to offer support, he said.
"You have your lycra louts ... those people who believe that it's more important that they keep their cadence at 35km an hour to meet their personal goals rather than slowing down for some children and their parents who are also trying to get to school and work safely," he said.

You can't argue with idiots like that, they ride in bunches all over the road blocking traffic discussing their lattes and you get abused if you try to pass them.
Millions have been spent on them yet they still think they are superior to others.
Cycling has developed a kind of green prestige or aura of virtue where riders seem to think they are morally superior to car users or, even more mildly, believe they have just as many rights to travel on publicly funded pathways as cardrivers. There’s some truth in this but it is not the whole story. Pedestrians have even less impact re sustainable lifestyle. It seems common sense that the lowest speed and therefore more vulnerable and least ecologically damaging travel mode should have right of way and take precedence.
