Opposed Traits Edit
Additional Info Edit
Like SLEAZY this never shows up on romantic npcs, unless you set it for a custom one. Crude mostly affects npc's talk - they swear much more and annoy Refined girls. However, crude men also don't hide how they feel. If they dislike you or are jerks, then they won't be able to fake being nice when they're trying to get you into bed.
