The playing style in "Gunz the duel" that relies on a dagger to kill opponents.
My friend taught me d-style and I learned how to yo-yo and own some nooblets.
1) A bowel movement of the wet and sloppy variety (i.e. diarrhea-style)
2) Any kind of bowel movement (i.e. dookie-style, dump-style, droppin-a-duce-style)
3) A nickname for a summer history intern (i.e. David Rosen)
"That catfish gave me some serious D-style!"
"Hey, D-style is wearing a cool seersucker jacket!"
