Answer and explanation:
The purpose of using dashes in this excerpt is to set off an appositive sentence that contains commas. An appositive sentence is a structure that offers further information on something mentioned before it. Appositives can usually be set off by commas but, when they are long and present commas in their own structure, they are set off by dashes.
In the excerpt we are studying here, the appositive "-so-called because they used to, like, DECLARE things to be true, okay, as opposed to other things are, like, totally, you know, not-" is a very long one and full of commas. It is supposed to offer further information on what declarative sentences are.

<u>Explanation:</u>
The story "Pyramus and Thisbe" is an act that has been written by William Shakespeare. The story is about the couple who are ill fated lovers. Because of this sadness and ill fate, Pyramus stabs his own heart with his sword and he bleeds a lot and dies. But one good thing that happens is that he sees the beautiful face of Thisbe before dying.
