duder 

When a girl is giving a guy head (or guy going down on a girl) and the guy guides the girl's head up and down his dick by sticking his pointer and middle fingers in her nose like a bowling ball. This is in reference to "the dude" from The Big Lebowski. Afterwords, the girl cooks the guy pancakes.

Sally was sucking dick at sucking dick so I took control and gave her a duder. Then that bitch made me some pancakes.
