more than one donut
"I would like 4 doni"
"What is doni"
"It means more than one donut, fucker."
Short for "What are you doing now?"
Doni was a mistake made in an AIM conversation. Instead of asking "What are you doing?", the person decided to shorted it to "Doin?". But, they happened to make a mistake and type "Doni?". From that point forward they coined the phrase "Doni?", not ony becasue they were otaku and it sounded japanese, but just because it sounded cool.
