Like thickness, but instead of saying how thick something is (vegetation, liquid someone's skull, etc), it says how thin it is. A crucial difference between "thininity" and "thickness" is that "thininity" implies something is very thin, while "thickness" implies something is very thick.
"Wow, you blended your milkshake for ages."
"I like them thin."
"I dread to even imagine the thininity of your milkshake."
"I dread to even imagine the thininity of your skull. Leave me alone."
"I like them thin."
