Etymology

Origin of bull1

First recorded in 1150–1200; Middle English bule, Old English bula; akin to Old Norse boli; Greek phallós “penis,” from a root meaning “to swell”; see bullock

Origin of bull2

First recorded in 1620–30; from Medieval Latin bulla “play, game, jest,” perhaps special use of Latin bulla “bubble”; now generally taken as a euphemistic shortening of bullshit

Origin of bull3

First recorded in 1250–1300; Middle English bull(e) “a (lead) seal affixed to a papal edict, papal edict; official sealed document,” from Medieval Latin bulla “seal, sealed document,” from Latin ; see origin at bulla

Explanation

A bull is a male cow. You can usually tell which animal in a pasture is a bull by its large size and horns. A male bovine — or cow — is a bull, and so is a male whale or elephant. Fittingly, the word bull is sometimes also used for a particularly bulky, muscular man. Another informal and slightly obscene meaning is "ridiculous," or "not true," as when you tell a lie and your brother rudely replies, "Bull!" This slang meaning has its roots in the Old French bole, "deception or trick."
