* Unpredictable: This is the most common meaning, often used to describe someone who is impulsive or acts in unexpected ways. Think of a squirrel darting around, changing directions quickly and seemingly without reason.
* Erratic: This relates to being inconsistent or unreliable. Someone who's squirrelly might be all over the place with their emotions, actions, or behavior.
* Nervous or anxious: This meaning is less common but still used, suggesting someone who is jittery, fidgety, or easily spooked.
Examples:
* "That new guy in the office is a little squirrelly; you never know what he's going to do." (unpredictable)
* "The market has been pretty squirrelly lately, going up and down all over the place." (erratic)
* "I felt squirrelly about giving that presentation, but it went fine." (nervous)
The exact meaning of "squirrelly" will depend on the context. It's often used informally and can sometimes have a slightly negative connotation, implying that someone isn't in control or is acting in a way that's unsettling.
