Answer:
What is peer pressure?
A peer is like a friend. Peer pressure is when the friend pressures you to do something.
Example:
You and your friends go out one night. You all see something that you know is wrong if you do it (ex. Smoking, drinking, rock concerts, tattoo etc). Your friends go, and invite you to join them, and you refuse, cause you know it's wrong.
Your friends then tell you that "Your not cool" or "If you don't go, you're not our friend anymore". They are pressuring you to join them.
And that's basically peer pressure, and believe me, I actually fell for it, but it was for rollercoasters, not smoking or drinking or all that stuff.
Hope this helps!
