Our reading
An editorial interpretation.
The speaker links the unpleasant smell of pus with the satisfaction of victory. Pausing before the final word gives the statement the shape of a triumphant declaration, despite its grotesque subject. The joke depends on treating something normally repellent as a welcome sign of success.
