werp (nown) dirt, rubbish, infection, junk, nonsense and pretty much everything else of that ilk.
werpish (adjective) scruffy, dirty, bad, too cold, too hot, smelly etc.
I woke up feeling distinctly werpish. I went to the bathroom and looked at my tongue. It was covered in werp. I felt sick and werped all over the basin. When my wife saw this she went into a real werpy mood. I rang my daughter and she was sympathetic but had problems of her own. Her partner, an amicable and unwerpish person, could not start his car because of a werped out battery. So he took her car which left her to walk to work in very werpish weather.
