The term "blimping out" does not have a well-established etymology as it is an informal expression that has emerged relatively recently. As such, it does not have a documented historical origin or a formal etymology. It is a slang phrase that is often used to describe someone who is overeating or excessively indulging in food, similar to "pigging out" or "stuffing one's face". The use of "blimping" in this context is likely a metaphorical extension of the noun "blimp", which refers to a type of non-rigid airship.
