Hi. Enormous nerd here to add some additional insight.
Arabella didn't just throw pig guts at Jude. She tossed "the characteristic part of a barrow pig." A barrow pig is a castrated male pig, and so the "characteristic part" would, in fact, be the pig's penis.
That's right: the meet cute between Arabella and Jude was her throwing a pig dick at his ear. She's a subtle one, that Arabella.
