Bwoink is used online as a general-purpose cartoon impact sound rather than a quote tied to one famous character or scene. Short boing-like effects have circulated for years in meme edits, gaming clips and low-effort comedy videos because they instantly signal something clumsy, weird or unserious. Its appeal comes from how fast and readable it is: one quick hit can sell a gag without covering dialogue. It also sits in the same editing family as simple comic accents like pop sfx and bonk-style sounds.
