Warning: These terms are not officially endorsed by Maxis nor Electronic Arts, and are not accepted on Mod The Sims. Use of them in conversation without clarification may lead to confusion in the greater community.

For more information on age-specific bugs, see main articles: Sims Not Acting Age-Appropriately and BI-SWILS.

Why do these distinctions matter?
Unlike twin baby glitches, which cannot be saved, instances of a Boddler can be saved before BI-SWILS is in full motion. Attempting to play Boddler-infected lots can result in BI-SWILS occurring immediately after loading, which can corrupt an entire lot and make that lot forever unplayable. If this unplayable lot is exported to a file, the file will be a virus which can corrupt other players' games.
