Perhaps「sticky liquids」(氺) written laterally for an obvious reason, but more likely「emissions in all directions on all sides of rod in horizontal motion」with a「net on a tray」that contains a poultice applied to a severe infection…「spurting shaft with emissions into bowl.」Reaming one's rod with a long splinter-like bougie will produce ALL THE MORE discharges of pent-up gleet to INCREASE FLOW. Conducting a close examination of the bandage, also referred to as a「dressing」filled with bodily emissions is BENEFICIAL, ADVANTAGEOUS, PROFITABLE for helping diagnose the problem, how advanced the disease has become, and for an assessment of the effectiveness of treatment. English definitions of「dressing」are all related due to this same medical practice, including the stuff oozing over one's salad plate of plants and leafy greens, and chopped chunks of bird, fowl meat giblets and cubes of absorbent bread packed inside the cavity of a turkey, perhaps the only other explanation of「sticky stuff on a plate.」
　Used today by accountants to denote net income and net gain, but formerly referred to a medical procedure that proved to be of tangible net benefit despite some costs and pain, the positive end result after considering all the plus and minus related items. Perhaps the resulting color caused by the original medical reaming process is why NET GAIN in Asia is depicted by accountants in red (color of healthy flowing blood), not green (color of gonorrheal gleet, accounting net loss in Asia), or black as it is in the West (color of melena, blood in feces).
　「Spurting shaft with emissions into dish」or into some sort of「trough」simply describes copulatory sex in one orifice or another with someone pretty, perhaps the source of English slang of the past century referring to a pretty girl as a「dish」and to「dish it out」as dispensing abuse. A dish is a shallow concave container used for purposes other than eating, or, holding something prior to eating, for a NET GAIN, INCREASED FLOW, and so on.「Trough」referent applies to a「dish licker」most likely, as a NET GAIN, INCREASED FLOW, ADVANTAGEOUS, BENEFICIAL as a prelude to some sort of fundamental activity. Licking a dish suggests something so good that one wants to eat every last drop or speck, considered vulgar behavior by those observing but most folks try it at some point in life nonetheless, a net gain overall.
