wiener 1. informal A frankfurter. Cooking wieners on the barbecue will always make me think of summertime as a kid. We're going to cook some wieners over an open fire, then roast marshmallows for dessert! 2. slang A weak, cowardly, or otherwise contemptible person.

"frankfurter," 1906, with slang sense of "penis" following soon after, from German wienerwurst "Vienna sausage" (see wiener). Meaning "ineffectual person, effeminate young man" is slang from 1963; pejorative sense via penis shape, or perhaps from weenie in the sense of "small" (see wee).
