When it's 'Mad Red Brick' outside people are referring to a lot of building work in the vicinity. Red brick dust in the air will make things Mad Red Brick. You'll have to go out with a mask on or you'll be coughing Mad Red Brick.
Geez Dweeble - it's mad red brick out today - I could have built a house with my boogers.
