Cryptic profanity and as applied, allusions are parallel. Allusions aren’t always profane.
Nothing at all that Shakespeare wrote was "cryptic"! His explicit descriptions of sex specific physical attributes, that many of his male characters say, though the words are NOT in common usage today, were extremely common when he wrote them in many different plays.
Though Jews had been barred from living in England for 100s of years, when Willie the Shake was writing, his anti-Semetic sentiment, in a few plays ( no, used NOT just against Shylock in THE MERCHANT OF VENICE !); especially in the Scottish Play ( nope, I never say nor spell out the title nor lead character of that play and if you have to ask why; you don't really know much about Shakespearean plays)and what the witches say!
Oaths? Using GOD's name?* Oooooooooooooooooooo...there are just tons and tons of them and not just GOD, but the Christ too;some are even combined with sexual stuff; you obviously 1) are NOT as familiar with all of Shakespeare's work 2) don't understand the words he used 3)are more than just a tad confused 4) all 3.
And now, to be a kind and helpful person, is a small list of books, which you should make yourself familiar with, by reading them!
THE ANNOTATED SHAKESPEARE, by A. L. Rouse ( a Brit authority on Shakespeare and several other subjects, whose Shakespeare bio is also quite good )
Naughty Shakespeare, by Michael Macrone
Witches and Jesuits, by Garry Wills
Shakespeare and the Jews, by James Shapiro
And should you require more books to read, I will gladly supply you with more titles, including those of my old college text, from a very extensive and fascinating class I had on Shakespeare.
