1. A female who, usually due to some small amount of popularity, becomes so extremely narcissistic, egotistical and self important that they truly believe everything they do and say is exceptional impacting and life changing. Anyone who doesn't kiss their ass, criticizes or disagrees with them is a hater, a bully or (if a man) a misogynist. A lot of times they suffer heavily from the Dunning-Kruger Effect.
2. A person who acts like such a massive cunt that their behavior not only draws everyone's attention to it, but it also negatively impacts everyone around them
1. Did you hear Madonna's speech at the Women's March? You would think she just cured cancer the way she talks. She has become such a significunt these days.
2. This lady on the plane refused to wear a mask, so the attendant asked her to leave the plane. Then she screamed, refused to leave the plane, and caused such a significunt problem, that all passengers were forced to de-board the plane and missed their connecting flights.

(personality)

a significunt is the right out faggot of your frienship group. however he/she is the one who does all the dirty jobs like, drive you home from a big night. if not for them you wouldnt have a way home or any spare change for that maccas meal. the reason they do this is so they can feel accepted.

they're significant in your friendship group, but they're still a cunt.

Person 1: Marks our significunt
