What I mean by that is...a tendency to express anger, frustration, etc. Feeling unable to contain oneself. A feeling of "if I don't get this off my chest, I will go crazy". Needing to express how you feel "right now".
Is this type-related or at least type-influenced?
Disclaimer: I only mean this in a personal context- assuming that you are speaking to someone you are close to and feel comfortable being yourself around. It does not pertain to more superficial interactions, such as at work or groups.
