To vomit and brazenly act as if it were not anything but de rigueur. Throwing up like it ain't no thang. Tossing one's cookies with an air of relaxation. Literally, a combination of vomit and non chalant.
DOOD: So listen, girl, I think you <yak! hwarf!!> lookin' real serious tonight, and I was wonderin' if you would be interested in accompanying me back to my crib.
DOODETTE: That was real Vom Chalant, and all, but I think I'll be fine at my own place.
