The stars (*) show it is an action.
The "brick'd" means a brick has been thrown at a peron.

*brick'd* means the speaker (on the internet, IM conversations, ect.) has gotten a brick thrown at him. This is not serious, of course- it usually follows something they say that would make them regret saying it, state an embarrassing obviousness, et cetera.

See shot.

In alternative, *bricks*/*brick* can be used in a two-person conversation over the internet/IM to say the speaker is throwing a brick at someone. In over three, *bricks 'name'* can be used to mean the same.
