A look which causes the human body to physically decintergrate from pain, causes the person receiving the look to feel as though they have been punched in the face. The greasy look is that of one which holds immense judgement and horror. (Basically a rude look but more severe)
Example: roly decided he would take a picture that he looked dreadfully disgusted in, as though he had seen a rotting corpse, causing the person receiving the picture to feel judged and afraid they sent him an accidental foot pic.
Example 2: âJessica shot me the fattest greasy this morning, I think sheâs pissed off at meâ
Example 3: âyou should have seen how many greasies he got, I was so embarrassed for himâ
