(Vad-nay) a word very commonly mispronounced. a word that describes a funny ass mother fuckin guy. one who likes to show their bodies in ways that someone might not want. also a vadnais could be mistaken for old man herbert the pervert from family guy. likes to sew and knit.
there is no example for a person being a vadnais. you just have to know or you miss out.
