Hi, Rusty!
I have heard of "blotto" meaning "drunk" but no, not "high".
The use of "high", I would associate with "high on drugs", maybe, or "high" as in "rancid"?
I love "blootered"!
I doubt, though, that I can introduce it into conversation....?
"Did you get blootered last night?" might not go down well on my morning walk!
Oh dear...I had enough trouble with today's crossword..... unlike you, I am not looking forward with much confidence to tomorrow's Championship offering!
Yes, daughter texted.....all well!
