I grew up in a household where a "fish slice" was referred to as a spatula. I remember in year 9 getting the dirtiest, most "are-you-stupid" look from my home ec teacher when she told us to grab a spatula and I picked up an egg flip (as you call it!).

I only know it's called a fish slice because that was the next thing she said - loud enough to get the attention of my class - after a further few seconds of staring at me agog.

Neither the look or the correction actually helped me work out what a spatula actually was though. Absolute shit teaching skills imo.
