1. Liquid that comes out of the penis when a male ejaculates. (semen)
More precisely, however, it is the residue left inside of a condom after someone is done having sex.
ie: Any leftover cum that is not used for the specific purpose of inducing pregnancy.
The term is derived from "wasted fuck", because the semen was not used for its primal purpose of making a baby.
2. A derogatory term for a jerk or a stupid person. (see synonyms douche, idiot, jackass, asshole, moron, worthless, etc.)
This indicates uselessness, because as you can tell from defenition number 1, "fuckwaste" is something that has no point in being there, so this easily translates into an insult.
