Can anyone tell me what drink I might have heard someone order?

Okay, so I know this is probably stupid but I tried googling all the potential options and can’t find anything similar.

I’m in Mexico and someone next to me at the bar ordered what sounded like, “iced confee with beer”

Now I know what you’re thinking, he said “coffee” and I misheard him, but I’m confident that he added the ‘n’ in the first word.

The drink definitely had beer in it. It was an iced drink that looked like watered down beer or whiskey (brown).

Any clues as to what he ordered? And yes, I should’ve asked the guy what it was but I wasn’t this curious until after I left the bar lol.
