Something that is so good, it makes you jizz. Usually refers to taste, appearance. Can be used to describe almost anything in the world. However, it is not commonly used to describe sex, as that is physically jizzalicious, and therefore kills the meaning.
adj. a non-derogatory term describing a state of being of sufficient weight to jiggle when one walks or performs other basic physical activities; roughly equivalent to 'pleasingly plump'
