What did Duncan do this time?

Duncan

A weeb that denies his existence, while simultaneously simping for Japanese women.

"Dan, don't be a Duncan. You promised to play D&D with us."
"Bro, anime isn't that cool. Don't be a Duncan."
"Fuck that guy. He's a total Duncan."
"I'm sure that Duncan likes his sangria with White Claw."
