Smacked? They have an odd way of describing a good ole spanking in the UK. But then in my home I refer to it as “Applying the board of education to his seat of knowledge”
A “smack” is a potch on the tush.
I used to get my fair share of spankings (and probably deserved them) and had a successful career and am now enjoying a great retirement (other then zero being in the WH)....OTOH my two nephews who NEVER got a hand to the backside are both spoiled and immature as hell. One has a great job as a government contractor but is lazy as hell otherwise and irresponsible and he’s 34; the other one works at Target (and as my brother said the other night “boy that English degree did him a lot of good).....and the only time my parents, my brother or I hears from either of them is when they’ve got their hand out....pitiful!
