If you're a "Troll" or "Trolling" on the internet, then you're a "Rolfsen", or a "Trolfsen"
Using the word Rolfsen is a more discrete way of saying troll, while pulling off a Trolfsen is ultimately the highest rank of trolling achievable.
Damn I felt like Rolfsen yesterday when Blizzard banned me.
Person 1: Trolfsen here went to talk about a loan in the bank yesterday.
Person 2:Lol, what do you need a loan for?
Person 1:I don't, the bank does ;)
