Bubbleblowers

"Bubbleblowers" is a playful nickname that snorkelers jokingly use to refer to open circuit scuba divers. It stems from the idea that scuba divers create bubbles as they exhale underwater. Snorkelers may use this term in a friendly and teasing manner, acknowledging the difference in equipment and diving techniques between the two groups.
