splurt
Sudden liquid ejection
Splurt is an informal, expressive word for liquid ejecting suddenly and messily—somewhere between a splash and a spurt.
It suggests a wet, splattering release: Ketchup splurted out of the bottle onto his shirt.
The noun describes the resulting mess or the sound itself.
The word is onomatopoeic, evoking the noise of something viscous escaping under pressure.
