Gaming analogy.

When someone's (usually a girlfriend's) anger is at it's crisis mode. They've shed their first and second stage attacks and phased into their highest level of fury. Nearly impossible to defeat, this screaming, rage-fueled bitch-monster will stop at nothing to ruin you.

Tread lightly. Her HP is at an all time high, so choose your weapons carefully:
Apologies, candies, and compliments often have a reverse effect and are weaker against a Final Form rage monster.
Man, she's scary enough when she's just mad, but last night that bitch went into her Final Form.

The last and most final form of the dog, usually comes in the appearance of Gabe the Dog, with barking and yapping in a similiar aspect. Very rare to happen, but it requires a lot of time.
That dog is transforming.... into the fabled Final Form Doggo!!!
