Senior school: Some teachers would cane or strap to almost sadistic levels, but the fun guys would just slipper. I’m remembering “Jack” the music teacher & “Joe” who did PE, whose lessons were a laugh throughout AND we actually learned stuff. You could be called out to get 1 whack with a plimsoll, your classmates soto voce singing “the whack,the whack, the order of the whack”and back you came shouting a lot-of-asterisks word. All part of the Colditz “who gets one over whom” mindset.
