Top definition
The small bubble of air caught in your gooch when entering an aquatic environment often causing a tickling sensation when it moves past your nuts/gooch/inner thigh. It is common for a gug bubble to originate as a fart.
I love the feeling of a good gug bubble when lowering myself into a hot bath.
