The Wardrobe

At the museum, you need to engage the security guard in an insult battle. What gets you this trophy is only using the optimal insults – specifically, four optimal insults in a row.

The optimal insults are:

1) You will never be half the guard your cousin is, that's for sure!
2) Behind you, an aortic dissection!
3) From the looks of things, the pumpkin shape on your skull is still visible
4) Perhaps your heart has been pierced by Cupid's arrow
5) Your Netflix subscription has been hacked

I think the Jar-Jar one also works.
