From Middle English toord, tord, from Old English tord (“piece of excrement, dung, filth ”), from Proto-Germanic *turdą (“mud, manure”), from Proto-Indo-European *der- (“to split, flay”). Cognate with Middle Dutch tord (“lump of excrement”), Old High German zort (“dung, excrement”), Old Norse torð- (“dung-”, in compounds), Old English tyrdel (“dropping, small piece of excrement”). More at tear, treddle.
turd (plural turds)
- (vulgar) A piece of solid animal or human feces.
- I went to the toilet to drop a turd.
- A pejorative term, typically directed at a person.
Whether it should be considered an especially vulgar insult is subject to judgment, but certainly it would have a broader acceptability than many vulgarities in common use today.
