Terd, unlike Turd, is actually a very small piece of fecal matter. It is generally about the size of a raisin (little bigger) and is a rarity among fecal matter. Even more rare than the watery shit know as diarrhea or "fountain shit
" as its known in my house. Terds are usually discovered days after coming into existence and are usually hardened by then and can be handled by hand used for practical jokes.
