Let me know here (in which case, my (and your) curiosity will probably get the best of us and we’ll Google them anyway).
And if you do, obviously know most of the things will probably be NSFW.
One thing I already know about and will be my contribution: Never, EVER Google “blue waffle”. You’ve been warned.
I would guess the Pittsburgh City Paper using its local designation/name of simply “the CP”. Odds are good that the results would not be good.
Tubgirl is the obvious one.
ETA NSFW of course.
Eww.
I’m officially off waffles for a while.

Although nowadays, most of the search results are parodies or simply references to the meme.
Some seemingly innocent things that I’ve searched for on Google images and not liked the results:
kitten (you get an image of a deformed cyclops kitten, or at least, you used to)
Xenakis (Greek composer, seems safe until you google-image-search him and get photos of him after an accident where he had half his face blown off)
Tasmanian devil (it seems many of them have a disease that causes big ugly sores, and you get pictures of that)
I’m not sure if most of those images I’ve mentioned are NSFW, but I’m sure not going to look them up again.
What’s the problem with this one? Found a lot of (Canadian Pacific) railroad photos, but nothing else interesting.
CP=child porn
There is no way in the world that Google would allow actual child porn to be linked to in its results. They value their reputation too much, and they have the means to protect it.
“Degloving injury”.
I would just as soon not even know the term, but I’m stuck with it, and now you are, too.
I second “tubgirl.” Seriously, tame your curiosity. This has been on the net for as long as there’s been a net and a million other people would second avoiding it if they were here.
Also, yes but on a different note, don’t google degloving or avulsion injury. Really don’t.
Llta
Find out real fast if Google will (still) link to kiddie porn or things purporting to be kiddie porn.
Degloving brought up a medical report:
Traumatic degloving lesion of penile and scrotal skin
With pics.
All that was said was “machine shop” and “accident”.
Yes, they did manage to stretch the still-attached skin over most of the injury and he eventually restored full voiding and sexual operation.
…demonstrating, once more, that some people just have to stick their hand in the fire to learn. 
Hey - I did NOT ask for images.
I saw the title of a medical report and wondered “What the hell do you do when presented with that!”.
So I clicked it.
Note I did not include a link.
I am polite. I am old-fashioned enough to think that still counts for something.
But did he ever speak again, even if just to murmur expletives?
I’m surprised. Not enough to try myself though because I figured
CP = S&M
which Google *does *index. Or so I’m told. Never tried it.
WHAT??? CP = S&M??? What the fuck??
