What does bloop mean?
A bloop is a short, low-pitched sound resembling a bubble bursting, a liquid gurgling, or something plopping into water. The word is unmistakably onomatopoeic — its rounded vowel and plosive ending mimic the very noise it describes — and it belongs firmly to informal register, showing up most often in casual speech, children's books, video game and film sound design, and comic writing rather than formal prose. In American baseball, bloop has taken on a specialized second life: a "bloop" or "bloop hit" is a weakly struck fly ball that pops up just beyond the infield and falls untouched between fielders, often resulting in a lucky single. Beyond the diamond, the word gained unexpected fame when a powerful, enigmatic underwater noise detected by hydrophones in the late 1990s was dubbed "the Bloop," briefly igniting speculation about giant sea creatures before it was attributed to icequakes. Whether describing a dripping faucet or a softly falling baseball, bloop is a vivid, playful word whose sound and sense are perfectly matched.
A short, low-pitched bubbling, gurgling, or plopping sound.
"We heard a bloop from the drain as the last of the water went down."
Chiefly informal and American; almost always used with the article "a" or in the plural.
Baseball: a softly hit ball that arcs just past the infield and drops for a base hit.
"His bloop fell between three converging fielders."
Usually heard in the phrase "bloop hit" or "bloop single."
Standard plural; used when referring to multiple instances of the sound or several such hits.
"The soundtrack was filled with cheerful bloops and beeps."
"Bloop" is one of those rare words you can hear just by reading it — and in 1997, ocean scientists recorded a mysterious ultra-loud underwater sound nicknamed "the Bloop" that fueled sea-monster theories for years.

Etymology of bloop
Bloop is an onomatopoeic formation of twentieth-century American English, coined to imitate the low, bubbly sound of liquid or a soft plop. It arose alongside similar imitative words like blip and plop and has no cognates in other languages, since it derives from imitation of sound rather than from any older root. Its use spread into baseball slang in the mid-twentieth century for softly hit, looping balls.
How bloop is actually used
Informal and chiefly American English; strongly onomatopoeic in feel, so it appears more in casual speech, sound design, and sports commentary than in formal writing.
