No. A beamish boy is one who makes you proud.
What we have in the White Hut is an embarrassment on every continent. He’s like a troll that crawled out from under a bridge and somehow managed to convince people that he was a handsome prince.

You are of course correct. I misremembered the context and thus misapplied the word.
In my defense I merely offer that I only have the poem committed to memory up to 'frumious bandersnatch'.
Beyond that point I must cheat. Or look it up. But that's usually enough to get me by.
Unless I cross paths with a poet. ;-)
