Coined by the late "AK" meaning to show great dis taste in an object, thing, place, person, action, etc. This word can also take the form of a adjective, noun, adverb, etc. Butternuts has the flavor of an old man that's got shriveled up dusted walnuts. Butternuts has the looks of 90 year old plastic supermodel that continues to get botox.
Ya bro, that movie got less than 65% on Rottentomatoes, it was so butternuts. Like lots of butter on those nuts, it was so bad

1. A completely unattractive woman that may have man-like features. Analagous to butterface, but seems like she might also possess testicles. Everything is attractive "but-her-nut."
Cain: She's really hot!
Abel: That chick's got a beard! She's a butternut.
