Waffle is language without meaning; blathering, babbling, droning. One might waffle throughout an essay or a presentation, when not having enough material, or needing to fill in time. The term may be derived from the Scots verb waff^[1] "to wave, fluctuate".^[2]

To waffle, particularly in the U.S., can also denote indecision about particular subjects, or changing one's mind frequently on a topic. Example: "Eoin always waffles when he's speaking to John on their podcast". To which John usually replies "Come on Eoin, come out with it!". It can be used as a derogatory term; to describe, for instance, a candidate or politician who is considered to easily switch sides on issues to curry political favor (i.e. "flip-flop"), as an easily flipped breakfast food with the same name – hence the waffle famously used to represent President Bill Clinton in the Doonesbury comic strip.^[3]
