The action of rolling down steep hills on a skateboard or longboard.

when you go out tagging(when you write names or words on various objects in graffiti).

A popular graffiti style which is most common used by lesser skilled graffiti artists with some exceptions. Bombing is sometimes a more preferred form of graffiti because it takes much less effort and time than wild styling or murals....and can still be made to look nice and get your name up.

Bombing isn't meant to be senseless vandalism, it is meant to be art just like other graffiti, but a lot simpler than wild styles etc.
