The exercise of self defense from an assailant in a conflict that was unecessarily raised, and predictably could have been entirely avoided. This is largely a consequence of the person exercising 'self defense' not/poorly assessing personal risks, a failure to practice conflict resolution skills, or by provoking the assailant.
John had practiced the Rittenhouse Defense by injuring the enraged female assailant after he kept hurling insults at her.

Used by member's of Britain's right wing Conservative Party as a last resort when they have no valid defense or comeback; especially during Prime Minister's Question Time.

Weak leader Rishi Sunak seems particularly fond of using it despite the argument being largely irrelevant now as Jeremy Corbyn no longer sits as a Labour party member.

Background:
The animosity towards Jeremy Corbyn stems from a successful smear campaign orchestrated by the Conservative party, especially during the 2019 election campaign where it was aided by the UK's overwhelmingly right wing media including the supposedly neutral BBC.
Example of The Corbyn Defense:

"Let's not forget that the opposition wanted Corbyn as Prime Minister"

Currently it is Annegret Kramp-Karrenbauer who you cannot take serious because she is a career horny wannabe chancellor.
In order to increase the probability to be nominated for the chancellor job she just ran for the office of the Secretary of Defense.
She does not have any military experience neither.
She is also known as “Mini Merkel” because people compare her limply incompetent politics with Merkel.
Now the Bundeswehr (German Military) is fucked up again.
1: Do you know the German Secretary of Defense?

2: Before it was Ursula von der Leyen. But van der Leyen is now Commission President of the EU.
Now the Secretary of Defense of Germany is Annegret Kramp-Karrenbauer.
What a difficult name, huh?
And again a limply person for an office next to Merkel.

Refers to a person's using the well-known prevalence of widespread fake/mass-advertising correspondence as an excuse for his not obeying/acknowledging a 100%-legitimate-but-unwelcome message he has received, such as a hefty bill, restraining order, or other upsetting/disappointing directive that he does not wish to comply with ("Well, it made no sense to me, so I honestly believed it was just a fake message, and simply shrugged it off"). The effectiveness and/or defense-worthiness of said practice --- and your chances of being let off the hook as a result --- can sometimes be further bolstered by "pre-innocentizing" yourself (such as frequently showing up in court for no reason and claiming every time that you'd received an order to appear, and then finally --- after being irritably told for the umpteenth time by the court-clerk that they'd never sent you a summons --- declaring in a frustrated huff, "Fine... well, I guess somebody's been playing sick jokes on me, so from now on I'm just gonna simply IGNORE any and all such notices I receive!") sometime before committing whatever infractions would likely result in said unwelcome orders, so that you can appear justified in your non-compliance with what you supposedly thought was yet another fake order.
I successfully used the spam/telemarketer defense when asked why I hadn't answered a court-summons; I just said, "Oh, that notice was REAL? Oh my --- well, I'd honestly believed it was a fake message... since I've had so many pushy telemarketers and con-men harass me --- sometimes even falsely claiming to be tax-auditors or law-enforcement personnel --- that I'd long ago adopted an 'ignore any and all such notices as fake' policy."

Needless escalation of a tense situation followed by victim-playing on the part of the person who escalated the situation when their escalation turns against them.
