The Welsh word for microwave is "meicrodon". It is derived from "meicro" meaning micro and "ton" meaning wave. However, "popty ping" is a colloquial and onomatopoeic way of saying microwave in Welsh. It literally translates to "pinging oven". While it is not the widely accepted word for microwave in Welsh, it is a creative variant that some people use, depending on the region of Wales they come from.
