A word for go out of control

Are you sure you mean "go out of control"?

"... but then you went out of control" would mean that the person started behaving wildly and couldn't be stopped.

Yes, I am 100% sure. I know who I'm speaking to and I know what my message is.

The person who I am speaking lost control over their emotions and behavior. However, the person didn't really go insane or get mad. Just simply lost control over the situation altogether.

If their behaviour became unmanageable in a disruptive or wild manner then "went out of control" is appropriate. It doesn't have to mean that they really went insane.

I'm looking for a short very casual word that has that "jargon" nuance. For instance; "get angry" can be replaced by "flip (out)", or 'flunk an exam' can be used instead of 'fail an exam'.

Hmmm. Sorry, after all that I cannot think of anything that clearly and specifically means "go out of control". There are a number of colloquial expressions, such as "go off the rails", "go haywire", "lose it", etc., that are similar but not quite the same. Hopefully someone else can think of something.
