2.
A Kumlin usually comes to parties or gatherings too late or at the last minute. They are wise, happy and are social persons with a lot of humor. A Kumlin also has a temper like no one else and love to argue about their opinions.
Person: "Okey! I am giving up this argue!"
Kumlin: "I said that I was right all the time."
Person: "God, you are such a Kumlin..."
