Blechy is slang for something that triggers a visceral 'ugh' reaction — food that's gone off, a texture that's all wrong, a smell you can't identify but definitely don't want to, or any situation that makes you wrinkle your nose involuntarily. It extends the exclamation 'blech' (an onomatopoeic sound of disgust) into an adjective, making it useful for describing the full range of revolting sensory experiences in a single word.

The leftover pasta had gone completely blechy by Thursday — she couldn't even get the lid off without gagging.
Origin: Derived from 'blech,' an American English interjection of disgust popularized in the mid-20th century, possibly influenced by Yiddish expressive speech patterns. Editorial expansion authored on Slangora.
