LORELAI: Rory, there are only two things that I totally trust in this entire world. The fact that I will never be able to understand what Charo is saying no matter how long she lives in this country – and you.
Charo (born Maria Martinez Molina Baeza in perhaps 1941) is a Spanish-American actress, comedian, and flamenco guitarist. In the late 1960s and 1970s Charo frequently appeared on American television as a guest star, and she has had a successful musical career in Latin America for five decades.
Her stage persona has an exuberant manner, wears flamboyant costumes, speaks broken English with a heavy Spanish accent, and uses the meaningless catchphrase “cuchi-cuchi” a lot – hence Lorelai’s difficulty in understanding her.
