The line comes from Big Clive, the electronics creator known for taking apart gadgets, torches and household devices in a calm workshop style. During one teardown he introduced an item as the soon to be moist internally thing, and the unintended innuendo made the moment stand out from his normally technical commentary. Shared as a short soundboard clip, it survives because the contrast is instantly clear even without the original video, giving creators a ready-made awkward reaction for wet, damp or accidentally suggestive scenes.
About this sound
Big Clive says soon to be moist internally while introducing a gadget, in a dry tone that sounds unintentionally rude and works as an awkward reaction clip.
In this short clip, Scottish electronics YouTuber Big Clive introduces an item he describes as soon to be moist internally, delivering the phrase in his calm, matter-of-fact workshop voice. The humour comes entirely from the unintended double meaning, because he says it completely straight while talking about a device that will get wet inside. Listeners tend to do a double take, then laugh at how innocent the context is compared with how suggestive the words sound on their own. It is brief, clear and easy to drop into a video just as an awkward moment needs a punchline.
