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
Person 2: Yeah
Mark: What was that?
