To vomit upon or cover with vomit; to spew all over.
From Old English 'be-' (prefix) + 'spew' (from Proto-Germanic 'spewaną,' meaning to vomit or eject). The prefix suggests a thorough coating or covering with the ejected matter.
Shakespeare and his contemporaries loved vivid, slightly gross words, and 'bespew' would fit perfectly into a revenge tragedy. It's the kind of word that makes you understand how Elizabethan audiences had different standards for theatrical language than we do today!
