Somebody whom hogs on to toilet paper rolls or goes around spitting saliva into each others mouth or touching dirty surfaces and stuffing it into others mouths.

That man over there is putting his finger into that lady's mouth. He is so sarstupid.

snapstupidity 

When you allow yourself to take a photo booth picture that can be viewed by a partner as infidelity over fun.

What is this woman you are hugging? What total snapstupidity. I never want a picture with you again.
