- 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 some 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?**
