Trait grumpy.png

Grumpy is a social trait in The Sims 3. It conflicts with the excitable and hot-headed traits, and is available from birth.

Grumpy Sims are rarely in a good mood. It's quite difficult to make them happy because they simply don't want to be happy.


  • Grumpy Sims will usually get sad before getting angry or uncomfortable.
  • It's more difficult to get the Sim into a good mood. To be specific, they take an innate and invisible -15 mood penalty.
  • Grumpy Sims have the option to "Troll on Forums" while on the computer. This will result in a positive moodlet if the trolling succeeds.
  • Grumpy Sims don't like to enthuse about something, they also don't like giving away compliments unless they have the charismatic, easily impressed or schmoozer traits.
  • Grumpy Sims may react bored to certain interactions like the "Woo!" interaction from party animals or the "Tell Funny Story" interaction.
  • Provides a bonus to Sims writing in the satire genre.
  • Grumpy Sims are prone to autonomously arguing with other Sims, but rarely escalate to insults or fights as hot-headed, mean spirited or inappropriate Sims will tend to do.
  • Grumpy Sims may scream out in fury if something bad happens to a nearby Sim or if something bad happens to themselves.
  • Grumpy Sims will autonomously use the "Complain About..." type interactions. This will grant them the positive "Let off Steam" moodlet if the interaction is accepted.
  • Grumpy Witch Sims will sometime autonomously cast malevolent spells and curses to another sims, greater chance while having the "Out of Sorts" moodlet.
  • Sims with the Grumpy trait may develop the "Out of Sorts" moodlet upon awakening, making them potentially angry.
  • Grumpy Sims will not react well to being splashed in a pool, and will furiously splash back at the offending Sim, decreasing the offending Sim's fun gain. They share this attribute with hot-headed and mean spirited Sims.
  • Grumpy Sims can be "Mock (over their Grumpiness)" by another Sim, which greatly decreases relationship between the two Sims.
  • Grumpy Sims will grumble while waiting for their turn when playing Hopscotch instead of cheering the player in turn like the rest of the non-Grumpy sims.
  • Grumpy Sims will autonomously "Shoo Off" cats sitting on top of furniture, even if the cat is asleep.
  • In addition to autonomously crying after having traumatic event such as the death of the closest one, Grumpy sims will also scream when remembering the dead sims.

Special Moodlets[]

Image Moodlet Name Notes
Out of Sorts.png Out Of Sorts Occasionally appears on grumpy Sims upon waking up. The "Out of Sorts" moodlet adds a -20 point penalty to the Sim's mood, and it typically lasts for 23 hours. Getting a good night's rest or meditating[TS3:WA] can help to alleviate this moodlet much faster. Neurotic Sims can also remove this moodlet through the use of the "Share Worries" interaction.
