I have never heard the second part, Poli, but as far as I know the first one means that the situation is heated and you must be careful what you say not to make things worse.(This is not the right moment to...)
Example situation:
The parents are fighting and the brother says to the sister:' Don't tell Dad now that you went to the disco yesterday or he'll go ballistic.'
