Curly is how I nicknamed him

But he doesn't look very curly on that concept art, his hair is too short.
I noticed Varric doesn't give silly names to serious people. He didn't make up anything for Hawke and Aveline, and he called Cassandra simply Seeker. He gave cute nicknames to cute girls, and with Bela it was just Rivaini, because that's all that is certain about her, I suspect. So I guess if he discovers something to tease Cullen about, he'll make a nickname based on that. What is the most funny thing about Cullen? Well, it used to be his Amell/Surana syndrome, but after he told Meredith to stand down, I'm not sure that kid is still there somewhere. So that's why I'm puzzled. No idea what Varric may identify as Cullen's most distinguishing feature. Hm, Curly may actually work.
I've asked for a reason. I have an idea for something silly, and I needed to find Varric's voice to make it work
