be in a huff

Of course, any party's backbenches are almost constitutionally set up to be in a huff.

He who would raise the passion of a judicious audience, says a learned critic, must be sure to take his hearers along with him; if they be in a calm, 'tis in vain for him to be in a huff: he must move them by degrees, and kindle with them; otherwise he will be in danger of setting his own heap of stubble on fire, and of burning out by himself, without warming the company that stand about him.

How could I get out of the room without appearing to be in a huff or bored?
