* "Aqui" means "here"
* "Un" means "a"
* "Amigo" means "friend"
* "Chica" means "girl"
The most likely intended meaning is: "Here's a friend, girl" or "Here's a friend for you, girl"
Here are some more grammatically correct ways to express this sentiment in Spanish:
* "Aquí tienes un amigo, chica." (Here's a friend for you, girl.)
* "Aquí hay un amigo para ti, chica." (Here is a friend for you, girl.)
* "Aquí tienes un amigo, amiga." (Here's a friend for you, friend.) This last option is a bit more respectful.
