taste-like-chicken

Verb

(most often used in present tense: tastes like chicken)

(simile, humorous) Comically describes the taste of unique food, deriving humour from the idea that many exotic meats, from squab to rattlesnake, can taste like ordinary chicken.
Ever had rabbit?
Yeah. It tastes like chicken.

Origin

Modern spices normally used in chicken lead to similar taste in exotic meats.
The similarity of proteins in chicken and other meats makes a similar taste inevitable. The common food becomes the benchmark.
