Dongwoo shouts, "From henceforth my name shall be OOWGNOD!" way too overzealously.

As Sunggyu stares at him judgmentally, "Right...and mine will be Alphabet Soup...Yeah, because that's what we're doing now..."

Like wtf, why the name change? Does Dongwoo have an alternate ego? Is he a superhero? Supervillain? Has he taken up a hobby of masked wrestling!? 

Also, it sounds like the name of a Norse god, doesn't it?
