Superlative form of gulpy; most inclined to gulp or most characterized by gulping.
From 'gulpy' with the superlative suffix '-est,' expressing the highest degree of the quality of gulping or eating in large swallows.
The superlative 'gulpiest' is almost never used in modern English, but it's grammatically perfect—it shows how English can theoretically create incredibly specific descriptions like 'the gulpiest eater at the table' even if we don't usually bother.
