'Red pill'

If you think you're going to get info on the "Matrix" movies by Googling this term, you're wrong. Instead, you'll get a glimpse into the Men's Rights movement; critics have called much of the movement misogynistic.

'Mouth larva'

If you're searching for pictures of moth larvae, be very careful not to accidentally type the word mouth instead.

Learning the basics of bedbugs and travel is probably a good idea. But if you're looking to avoid stress, maybe not. Five minutes of exposure to the warning signs of bedbugs could convince even discerning people that these six-legged intruders are hiding in their bedding. Exhibit A: Within a day of googling "bedbugs," we threw away perfectly good sheets. That's $45 we'll never get back.

'Murder Island Thailand'

Seven tourists have died on the small resort island of Koh Tao in the past three years under disputed circumstances -- a fact you'll learn if you Google the term above. As with Snapewives, we spent about two hours riveted by this rabbit hole of a story. That's two hours we'll never get back.

Like Samantha Bee's show, the phrase that makes up the show title "I Love Dick" is difficult to Google without graphic consequences. We recommend adding "Amazon Prime streaming video" to your search terms to watch this comedy.

[Your favorite thing] + 'cancer'

Googling your favorite things, from pizza crust to grilled steak, followed by the word "cancer," will likely yield at least one shaky report linking that thing and the disease. Even owning a dog has been linked to cancer by some sites... and we don't want you getting rid of your dog.
