Slob These Sims gain positive moodlets when surrounded by filth, and take much longer to trigger the Uncomfortable Emotion if they do so at all. They also make objects such as counters and sinks dirtier faster from use. However, they draw no penalties from being in a clean environment.

Snob These Sims draw penalties for being around anything they deem low-quality, such as food or art. They trigger the Confidence Emotion just by being in the presence of other Snobs. This is a dangerous trait to pair with Slob.
