What do you call a liquid that increases in viscosity as temperature increases

I want to know what do you call the phenomenon where a liquid increases in viscosity as temperature increases (meaning it gets stiffer and less runny the hotter it gets) Please answer this only if you actually know what you are talking about

Fragile liquids (I think). They do not obey the Arrhenius law.(i.e. temperature increase causes decrease in viscosity).
