In the past, I experienced long periods of hypomanias that sometimes rose to full manias. Impulsity was a major symptom for me during those times, especially when it came to what flowed from my mouth, or fingers, to a lesser degree. Throughout my life I have generally been an assertive and expansive type person. That's part of my personality, but mood elevation amplifies it. That's lost me friends, prevented some new ones, created scenes in public, made me seem very odd (wild)/over-the-top/flirtatious, resulted in disciplinary counselings, scared a therapist into quitting me, nearly got me fired, and led a pharmacist to nearly call the police on me. It was mostly all way "over the top" stuff or me expressing my desires, opinions and frustrations too openly and/or aggressively.

In more recent years, my insight into the above (and self control) has improved, but in the past it was very little and often absent far after-the-fact. Grandiosity/elevated self esteem during hypomanias/manias was often a contributing factor.
