Forsooth, in pass'ed times, when derivations and defamations were thrice socially acceptable, ye olde opus, by the Lauret, William Shakespeare, Romeo & Juliet spake forth of great silliness. Among this tome's mighty characters was one Benvolio.
Thus, 13-year-olds in England were forc'ed to read of his stupidity and demise as part of their schooling, and thence cameth the childish and generally un-funny slur, 'Bumholio'.
Comic genius it aint. Aye me.
Kid: I hate Shakespeare. Miss, why do we have to read this? It's nonsense!
Teacher: STFU, Bumholio.
