The grimace scale (GS), sometimes called the grimace score, is a method of assessing the occurrence or severity of pain experienced by non-human animals according to objective and blinded scoring of facial expressions, as is done routinely for the measurement of pain in non-verbal humans.
“If Grimace is a taste bud meant to show how good the food is why on earth would you name the damn thing after an expression of disgust,” another Twitter user pointed out. His feet are light ...
