Geek
Geek is a sim trait
These Sims become Happy when Reading Sci-Fi or Playing Video Games, may become Tense if they haven't played much, are better at finding Collectibles, and can Discuss Geek Things with other Geek Sims.
Geek can help Sims get Focused for using the Programming Skill to Make Video Games or even using Handiness. They'll get a Focused buff after finishing a game playing session with this trait. Based on the description, it's presumable that this increases the likelihood that your Sim finds rare collectibles from digging and finding frogs.
