Golly! Zounds! Gadzooks! These are the kind of things Captain Marvel would say. Almost any other superhero would be too mature for such, childish silly words. And yet, during Shakespeare's time, they made him one of the more edgy writers out there.
They're not just random sounds, but contractions, meant to make absolutely shocking sentiments less outright obscene. Golly, zounds, and gadzooks were, in order, god's body, god's wounds, and god's hocks. While thinking about the Almighty's ham hock region might offend a few people, each of these words are the kind of things now deemed perfectly innocent. This shows a huge shift in social mores since the time of the Shakespeare.
Religious obscenities, when half of Europe was at war with the other half over the right way to practice Christianity, were a big deal. Referring to God in the corporeal sense was a way to scandalize people. To take the Lord's name in vain was to go against explicit Biblical instructions. These were some of the more obscene concepts of the age, but today are the most mild swear words most people can think of.
