What does bulging mean?
"Bulging" describes something swelling or protruding outward in a rounded lump beyond its normal surface. It functions chiefly as the present participle and adjective form of the verb "bulge," applying equally to solid objects and body parts: a bulging mattress seam, bulging biceps, or bulging eyes. It also frequently describes containers or receptacles that are so full they appear strained — a bulging wallet, suitcase, or file folder — where it carries a connotation of abundance or overfullness. The word is standard in both British and American English and sits comfortably in everyday as well as literary registers, lending descriptions a vivid, physical immediacy. Its synonyms include swollen, protruding, and distended, while its opposites run toward sunken, flat, or hollow. Etymologically it descends from the Latin "bulga," a leather bag, making it a distant cousin of "budget." Whether evoking pressure, plenty, or strain, "bulging" remains one of English's most tactile words for things pushed beyond their bounds.
Swelling or protruding outward beyond the surrounding surface in a rounded lump.

Often attributive, especially before nouns like eyes, muscles, pockets, and files.
Present participle of "bulge": to swell or curve outward, or to cause something to do so.

'Budget' literally means 'little leather bag' — the same Latin root, bulga, that gave us 'bulge', which once described exactly that: a swollen pouch.

Etymology of bulging
The word traces back to the Latin "bulga," meaning a leathery bag or knapsack, likely borrowed from Gaulish. It entered Middle English in the medieval period, initially denoting a swollen or protruding part, and the verb "to bulge" developed later, becoming well established by the early modern period. The same Latin root produced Old French "bougette," a small bag, which evolved into the English word "budget"; the nautical term "bilge" arose as a variant of "bulge."
