Investurbate 

When you can't determine whether something is hot or not, so you decide to put it to the masturbatory test.

I'm 50% certain this HomeGoods ad is heating me up, but I'm not sure. Time to investurbate.

Yahoo Answers couldn't tell me whether or not I'm sexually attracted to Ansel Adams' photographs, so I had to do some ground-level investurbation. I'm not. We're good.
