Don’t Get into a Tiswas

“Today Is Saturday: Watch And Smile”
This was a children’s television program on ITV between 1974 and 1982. I never saw it.
tiswas
in British English
(ˈtɪzˌwɒz) NOUN a state of anxiety, confusion or excitement
Collins English Dictionary
The phrase that I heard was a variation on “Don’t get your knickers in a twist.”
Some claim that it is a contraction of ‘it+is+was’. That’s how I’ve always interpreted the word.
