Rocking

Usually goes with the word 'it' afterwards, you must make clear what 'it' is. To be rocking (it) means that you are using something or doing something, or 'going with' something, be it a weapon on a video game or an object or thing in real life. It depends on what 'it' is. you must make clear what it is that you are 'rocking,' in order for 'rocking' to be used as a phrase in context and everyday conversation. It can also refer to an item of clothing or a particular fashion look. It can be used to describe someone who is doing really well at something too. (for a video game it can also be another way of saying 'Im running with this...' for example for C.O.D it's like saying 'Im running with this class...' Instead you say 'Im rocking the sniper class for this game...' etc.)
