I like the word “knackered“. It seems particularly British to me. Sometimes I would describe myself this way but it’s because I go to bed way too late. Ya know what, everybody should make sure they get enough sleep. It really does make everything better when you rest.
Here is a poem for no reason:
Oh boy, it’s time for bed
This long day has me knackered.
Haven’t eaten all day
Does this mean I’m snackered?
Is Aaron Rogers Packered?
I just build this table,
It should probably be lacquered.
Just This Thing
