In a funny Top 10 list created by the popular TV show Spring of Trivia, a team of researchers went through the pages of 10,000 middle school textbooks and tallied what kind of graffiti was the most common. Among them — bloody noses, unibrows, forehead wrinkles, faux wigs, and the #1 most common type of textbook graffiti = speech bubbles.

can someone please explain why #10 is the kanji for meat on people's foreheads!?

It's most likely a reference to the popular 80s manga Kinnikuman. I think in US the cartoon version is called Ultimate Muscle. The main character is a wrestler with that mark on his forehead.
