Slang for buttered; a means of serving cafenated beverages with a buttered glass. This quaint method of drink decanting originates from the outlying areas of Northern Ireland, where it remains popular to this day. The glass is lightly coated with a thin layer of butter before the beverage is added, this gives the drink a fuller flavour and a slightly oily film on the surface of the liquid.
Barkeep, a coke 'terd my good man.

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.
