Divided by a common language indeed. This is fun.
Another Brit here.
A complete punishment could be:
- a smacked bottom
- a smacking
- a hiding
- a leathering
- a slippering
- a skelping
- a belting
- a caning
- a spanking
- the cane
- the slipper
all prefixed good which always means bad
An individual blow is
- smack but never spank
- slap
- whack
As a verb I'd say
- smack ( 1 or more)
- spank
- wallop
- leather
- slap (1)
- cane
- belt
- slipper
10 spankings sounds scary.
occasionally it was more specific.
- slap you legs (meaning several slaps)
- slap your face
Don't start on the euphemisms. Do I have to ....
- put you over my knee
- take your pants down
- take you knickers down
- warm your tail
The never have to. ;)
