How say q tal chiko in English?

"Q tal chiko" is Spanish slang. A direct translation doesn't capture the nuance. Depending on context and tone, it could mean something like:

* "What's up, dude?" (casual, friendly)

* "Hey man, what's going on?" (slightly more formal than the above)

* "How's it going, buddy?" (friendlier than "What's up?")

The best translation depends on the specific situation and your relationship with the person you're talking to.
