Budge and bulge swap one letter and share nothing else. To budge is to move the smallest real amount — and English uses it almost only for refusal: the jar won't budge, he refused to budge an inch. To bulge is to swell outward at one spot, into a rounded lump: pockets bulge with coins, a wall bulges where water presses behind it. Budge is about (not) moving; bulge is about swelling.
Budge came from French bouger, 'to stir', and turned into a negative-polarity specialist: nobody praises a door for budging — the word exists for the moment something should move and doesn't, in matter or in negotiation. Bulge came from Latin bulga, 'a leather bag', and kept the image of something stuffed until its skin strains: one definite outward bump while the rest stays flat. The single letter between them separates stubbornness from swelling.
budge
To budge is to move the smallest real amount — and English keeps the word almost entirely for the failure of that: the jar will not budge, the markets refuse to budge, he would not budge an inch. From French bouger, 'to stir', the verb is a negative-polarity specialist; nobody praises a door for budging. It transfers straight to people and positions, where refusing to budge means refusing the smallest concession, and British English adds the friendly imperative budge up — shift along and make room.
bulge
To bulge is to swell outward at one spot — a single rounded lump pushing out of a surface while the rest stays flat. Pockets bulge with coins, a wall bulges where water presses behind it, eyes bulge with surprise. It comes from Latin bulga, 'a leather bag', and keeps that image of something stuffed until it strains its skin. Unlike distend, which stretches a whole vessel taut, a bulge is local; unlike a plain swell, it names the shape — a definite outward bump.

The boulder and the bump. Budge is the bulldozer's afternoon: all that force, and the boulder concedes a thumb-width — the word lives in exactly that gap between effort and movement, which is why it nearly always arrives with a negative. Bulge is the capped hose: pressure with nowhere to go finds one weak spot and pushes out a single taut bump. Nothing about a bulge moves anywhere; nothing about budging swells. One letter, two different kinds of physics.

Budge is a negative-polarity verb: it wants won't, refuse to, barely, not an inch — 'the rock budged easily' sounds wrong because the word exists for failure to move. British English adds the cheerful exception budge up ('make room'). Bulge's traps are spelling: bulging drops the e, and 'buldge' — with an intruding d — is a common enough slip to be its own search query.
