Fun expression of the day: “flip a coil”

There is supposedly an Afrikaans expression that translates as “flipping a coil” or “flipping the cone”, etc. Kind of a more evocative equivalent to “shitting a brick”. It refers to the act of turning one’s underwear inside-out to dump out the results of having shit one’s pants, e.g. due to extreme rage or surprise. The imagery of course is of the canonical cartoon representation of a pile of poop as a conical coil, bearing an uncanny resemblance to the top of a soft-serve ice cream.

“Johnson is totally gonna flip a cone when the paternity test results come back.”

I wonder if this is somehow the origin of similar English expressions such as “flip out” or “flip your shit”.
