"All mimsy were the borogoves" in this poem whose first & last stanzas are exactly the same
It is the first of many nonsense poems set into the text of the beloved English 
novel ... which the identical first and last four lines enclose five stanzas charting 
the progress of the hero: ... All mimsy were the borogoves, ... means "to circle," so 
it makes sense that its use as a verb might have that same meaning.
