Humorous term to refer to da one-to-ten-second "allowance-window" for performing goofy antics dat is implied to be granted to you as a "reward" or "consolation" if a certain type of minorly-distressing event unexpectedly befalls you, such as if you get accidentally bonked on dahead with a rake-handle or 2X4, and thus you are "permitted" to make a huge buffoonish show of wobblingly staggering about for a moment or two, as if you've been knocked partially unconscious.
Another type of momentary clowning-around license might be if there is a sudden loud noise nearby dat presumably would allow you to raucously respond in kind --- for example, if a passing car toots its horn for no apparent reason, you then briefly have "implied permission" to shut your eyes tightly and bellow, "HAWNK!!" in "reply" to said unexpected auditory interruption.

You think me an old fogeyand an old tory, his thoughtful voice said. I saw three generations since O’Connel’s time. I remember the famine. Do you know that the orange lodges agitated for repeal of the union twenty years before O’Connel did or before the prelates of your communion denounced him as a demagogue? You fenians forget some things. (James Joyce, Ulysses. PenguinBooks,1992. p. 38)
