1) (noun); How one 'rolls'.

This can be loosely used to describe a mood, situation or routine behaviour (usually social).

2) (verb); to act out these behaviours or moods.
This is often associated with (but not limited to) exhibiting dominance in prowess of either physical strength (e.g. muscle size by FLEXING your arms) or cultural knowledge - namely dressing and dancing to impress and demonstrating a superior capability of use of language.

This is usually a playful display and is a part of innocent courtship, although it can be taken to mean a more sinister and aggressive stance.
