On the Foodgasm thread, Bishmillsneat object to the construction of "foodgasm" as, he says, the "operative suffix here would be '-asm,' not '-gasm.'"

Dictionary.com offers another -asm word: prograsm. This is defined as "The euphoria experienced upon the completion of a program or other computer-related project." The provenance is claimed to be the University of Wisconsin (which apparently has a Department of Geeks).

Here is an example of a new word built on the proper suffix. There are, perhaps, other -gasm words, built on the misconception that the proper suffix is -gasm rather than -asm.
