ds + dw

ds + dw (also dsw) is short for dogshit and dogwater, both terms used to describe someone's atrocious performance in a game but can be also extended to pretty much anything where someone has failed to meet even rock bottom expectations.

Best used in combination with words such like, ratio, cope, seethe, shiver etc.

Even better if the holy trinity of ds + dw + dp is used (last one stands for dogpiss), may also shorten it to dswp (not to be confused with the total cringe that is dsmp)
