- I look like a weapon if you know how to handle me (Edit)
- 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
- I am indivisible but I can become something else if you mutilate me (edit)
- I am often the beginning of the endsome ends, but I am not the apocalypse (edited)
- My grandgrandfather spirit is hidden in multiple things, like trees
- I've been 16 for long time now, but that depends on the mood, on self-confident days I pretend I am 80, on miserable ones 112, etc...
What am I?
