The hairdryer treatment.
A phrase used to describe the tongue-lashing one manager gave to his players.
That manager was, of course, Sir Alex Ferguson.
The legendary Scottish boss led Manchester United to 13 league titles and had his own special way of berating his players.
But what was it like having Ferguson as your manager?
Well, Ryan Giggs has revealed all and has admitted that it was a little bit scary.
"Fergie was scary and even now he still scares me,” said Giggs per the Mirror.
“I still call him boss because he just has that aura about him. He had that little cough and as soon as you heard that, walking down the corridor at the training ground, you’d dive in a doorway to get out of his way.
“I was always wary of him because he had that ability to turn up at your house – and he sometimes did.
“But he did it all for you and he had so many other great qualities.
Recently, Ferguson insisted that he had only used the hairdryer treatment “half a dozen” times.
However, that’s a claim that Giggs really doesn’t agree with.
“He said recently he only ever used the hairdryer half a dozen times – but I think his memory is selective on that! It wasn’t nice to get it, even as an experienced player,” the Welshman said.
And the former winger has also explained what happened if a player ever argued back at him - and recalls the time he did once.
“There was no point trying to argue with him. I did argue back twice, but it didn’t go well," he said.
“The first time was against Juventus away. They were a very good team and, at half-time, I half-questioned him – and got substituted there and then!
“I did it again, though, because, when you are playing and in the midst of it, the adrenalin is going with you as well.
“We were all winners, so if you wanted to make a point and put it across, you would.
“Half the time I’d be sat next to Becks and he would be whispering, ‘Be quiet, be quiet’, if I said something back, and I’d do the same.
“You could never win – but we still said our bit."
Recently, Patrice Evra claimed the only player that escaped a Ferguson hairdryer treatment was Paul Scholes. However, Giggs claims that it was another club legend that was never felt that wrath of Ferguson.
“Eric got away with murder – he never got the hairdryer," he revealed.
“We’d go to a black-tie do, my tie wouldn’t be straight or Nicky Butt’s top button undone and he’d rip into us.
“The next minute Eric would walk in with a white linen suit and red trainers and Sir Alex would turn to us and say, ‘Look at that – that’s style!’
“Me and Nicky would be going to each other, ‘For f***’s sake!"
