This occurs when a female placed several tablets of alkaseltzer in 'bottom' then an uncapped cola beverage is inserted and the whole affair is turned upside down draining the contents of the bottle onto the waiting alkaseltzer. Bloating and 'blimping' occurs immediately following. The recipient enjoys a luke warm beverage 'al a blimpy'.
Damn, that's the freshest blimpy I've had in hours!!
The definition of a blimpy/blimpie is not the same as a blumpkin contrary to popular belief. To perform a blimpy one must be uncircumcised. When your friend passes out, the uncircumcised skin is to be placed over the nose and their mouth is to be plugged up so that when the unwilling participant breathes through his nose it causes the foreskin to inflate. This is a true blimpy.
Why is that when a bunch of white guys hangout they always do some borderline gay shit like giving their friend a blimpy?!
