What does bitchy mean?
'Bitchy' is an informal adjective describing remarks or behaviour that are deliberately spiteful, snide, or maliciously critical — often in a petty, personal way rather than through open aggression. A bitchy comment cuts with insinuation or backhanded praise; a bitchy mood simply means someone is irritable and short-tempered, a sense especially common in British English. The word derives from 'bitch', originally a neutral term for a female dog that became an insult when applied to women, and its adjective form emerged in twentieth-century slang before spreading widely in casual speech and journalism. Though now firmly established and frequently used of both men and women, it retains mildly vulgar overtones and is best avoided in formal contexts. Its closest synonym is 'catty', which carries a similarly sneering connotation but lacks the secondary 'irritable' sense. Vivid and instantly understood, 'bitchy' is a useful word precisely because it names a very specific kind of unkindness: the sharp-tongued, under-the-breach variety.
Spiteful, maliciously critical, or deliberately hurtful in manner or remark.
"He made a few bitchy remarks about her new haircut."
Informal; mildly vulgar in origin.
(Informal) Irritable or bad-tempered.
"Don't mind him — he's just feeling bitchy today."
Chiefly British and informal American usage.
Born as a crude insult and tamed into everyday slang, 'bitchy' is one of the few English words whose figurative meaning has almost completely eclipsed its literal root.

Etymology of bitchy
Bitchy is formed from 'bitch', an Old English word (bicce) for a female dog that acquired derogatory human senses from late Middle English onward. The adjective arose in early twentieth-century English slang, first attested around the 1920s–30s, initially in American usage before spreading to British English. It shares its root with the noun 'bitch', the verb 'to bitch' (to complain), and derivatives such as 'bitchiness'. No cognates outside Germanic are relevant, as the base word is native English.

How bitchy is actually used
Informal and colloquial in all registers. Because it derives from an obscene term for a female dog applied derogatorily to women, some consider it mildly vulgar or sexist; avoid in formal writing. The second sense ('irritable') is chiefly British and informal American usage, and is not inherently gendered.
Easily confused with bitchy
Both mean spiteful about others, but 'catty' implies sly, feline-style sniping while 'bitchy' is broader and can also mean irritable or bad-tempered.
