This is a question I have been thinking about for three years and I have never seen it properly addressed. Everyone just talks about the gock pump as if its taxonomic classification is obvious. It is not obvious. It is not obvious at all.
There are two possible positions:
Position A: The gock pump is a subset of the regular pump. Under this framework, the gock is simply a pump that occurs under specific conditions (neck/cervical exercises, particular rep ranges, specific mental states). It is a pump. It is just a special, rare, intense pump. Like how a supernova is a type of star explosion. Same category, extreme instance.
Position B: The gock pump is a fundamentally different phenomenon. Under this framework, the gock merely shares superficial characteristics with the regular pump (blood flow, muscle engagement, physical sensation) but is ontologically distinct. It is not a pump at all. It is something else entirely that happens to occur during pumping activities. Like how lightning and a lamp both produce light but are fundamentally different phenomena.
I lean toward Position B but I want to hear arguments. This matters for how we talk about the gock, how we research it, and how we teach it to newcomers. Taxonomy is not pedantic. Taxonomy is foundational.
