- I can be a weapon if you know how to handle me
 - I am most popular than any other
 - People use me often when they want to be informal
 - Dirty minds see something lascivious in me
 - I am loved by road trippers
 - Some isolated people in the world have never seen me
 - I am man-made and when I am with my friends I can enlighten you
 - I have trillions of twins, but they are mostly fraternal twins

**What am I?**
