It is pronounced as /fɪz aʊt/, with the "f" sound followed by the short "i" sound in "sit" and then the "z" sound.

Fizz out is a phrasal verb that typically conveys the idea of losing energy or intensity gradually, leading to a weak or unsuccessful conclusion. This term is commonly used to describe the diminishing or declining of enthusiasm, excitement, or interest over time, resulting in the termination of an activity, event, or endeavor with underwhelming results.
The term "fizz out" originates from the notion of a carbonated beverage losing its effervescence or bubbling intensity, eventually becoming a flat and unappealing drink. Similarly, when an idea, plan, or situation fizzles out, it lacks the vibrancy, momentum, or follow-through required to reach a satisfying or successful outcome.
"Fizz out" can also refer to a sudden or unexpected loss of power or effectiveness. For instance, a machine or device that starts malfunctioning or stops working abruptly can be said to fizzle out.
In social contexts, this expression can be used to describe how interpersonal relationships or social interactions lose their initial spark or excitement, resulting in a diminishing connection or interest between individuals.
Overall, "fizz out" denotes a gradual or sudden decline in energy, enthusiasm, or effectiveness, leading to mediocrity, failure, or an unfulfilled conclusion. Thus, it signifies the dissipation or termination of something with unsatisfactory or lackluster results.
The phrase "fizz out" is derived from combining two separate words: "fizz" and "out".
1. "Fizz": The term "fizz" originated in the late 17th century and is onomatopoeic, imitating the sound of a hissing or bubbling noise. It represents the sound made when carbonated drinks release gas, such as the tiny bubbles of carbon dioxide escaping from a soft drink.
2. "Out": The word "out" is a straightforward adverb used to indicate something ceasing or ending.
When combined, "fizz out" refers to the gradual loss of energy or momentum, similar to how a carbonated drink loses its bubbles and goes flat. It is often used to describe actions, events, or processes that start energetically or with great enthusiasm, but eventually dwindle or end weakly or disappointingly.
