Great Balls Of Fire!
Back in year 9 I studied Electronics as one of my 4 "options" at school. We had this great teacher that would make us etch our circuit boards from scratch, using plastic B&W templates, light sensitive chemicals, and acid etc etc. The final step was to lacquer the circuit board and leave them to dry for 2-3 days until the next lesson.

About 2 weeks prior, this amazing, eccentric teacher of mine showed us how normal steel could catch fire. He place a couple of fibers of steel wool across 2 car battery terminals and WOOF! Up she went.

So I'm at class and everyone is gathered around teach as he explains something. Being my usual easily bored self I wander off unseen, where I spy a HUMONGOUS ball of steel wool next to a car battery. You know what happens next....

This huge ball of steel wool, about 30cm in diameter, instantly becomes an inferno in my hands. In a panic I randomly toss it across the room and it lands SMACK BANG in a pile of 30 freshly lacquered circuit boards from the previous class, laying out to dry.

Amazingly.... AMAZINGLY.... this whole 3-ring circus act went undetected by teach and my fellow students [the burning steel didn't smell like, say, paper would smell, and it burned very quickly]. I'm guessing I ruined at least ¼ of the circuit boards, but I wasn't exactly going to be making enquiries over the next few days so don't quote me. One of the best get-out-of-jail-free moments of my life.

As this is a story from your school days, I feel fully justified in issuing "chinny reckon" as a response.

If you disbelieve someone in the playground,
You can sarcastically agree whilst saying "Yeah, I reckon!" and scratching your chin theatrically. "Chinny Reckon!" is a variation on this theme.

Or I Could Have Googled "Chinny Reckon".....
So you don't believe me? Fair enough. I still don't know how anyone didn't see anything.

I totally rule.

Once I'd gotten to secondary school, "chinny reckon" had been replaced with the slightly more succinct "beard!", and the chin-stroking action was lost.
We then found some pricks in the year below us had turned that into "barbe" which, if anything, sounded even more stupid.

Jimmy Hill!
Chinny Reckon derives from the footballer Jimmy Hill, who was disbelieved for reasons I never knew and had an abnormally large chin: www.childofthe1980s.com/2008/01/18/chinny-reckon/

Just in case you wondered.

I always thought it came from stroking your imaginary beard, that had grown out whilst the object of your mockery told their unbelievable tale,
and Jimmy Hill got associated as you'd coincidentally be miming the shape of his chin.

always thought it
was a bastardization of 'BY NEPTUNES GREEN BEARD!' which I guess you would exclaim if you were an offended gentleman in one of those leather seated book club thingies.

Careful. My friend went to karate classes, and learned how to do a death punch.
He's not allowed to show us, though.
