“Chi chi” in Jamaica means gay. Just so you know.
Really? I know it’s also a nickname.

“Chiches” is a word in Spanish used in Mexico for breasts. “Chichi” is also used.
I’ve heard the word “chi chi” in Mexico, but not “chi chi bar.” I just added the fact about Jamaican patois for contrast. Just thought it might be a good factoid to file away in case you ever go to the Caribbean. You’re likely to be decapitated if you ask for a chi chi bar in Jamaica.
Around here (Jalisco) “chichis” is the far more common form.

I stopped in Calexico (and Mexicali) and it was easy to forget when you had crossed the border. This was long before Homeland Security, thankfully. My visit was a very enjoyable experience. There was a thriving chinatown in Mexicali when I was there, a fact which delighted this unsophisticated Bakersfield native.
