This question is inspired by the question of whether there is a single term for the sports surfing, skateboarding, and snowboarding.
I think many native speakers would read this question and think the answer is "board sports", similar to how the question "What is a term for all the windows of a house?" would elicit the term "house windows".
When I searched Google, there was an overwhelming number of results for "board sports" that came from retailers of the said item type, but no dictionary entries (please correct me if I'm wrong). The term "board sports" seems "obvious" in the same way that the compound "front door" is, but this is a dictionary term.
Is there a term for an "obvious" but not (dictionary-)"accepted" compound/term such as "board sports"? I think it might be something like "lexical gap", but 865,000 results on Google when searching "board sports" with quotation marks suggests that the gap might be considered filled.
