A chicanoism that translates in English to "Just to let you know", or "Just so you're aware".
Many Californians and residents of Southwest states will not even recognize this phrase as regional or colloquial, and will in fact believe that it is an English phrase. It is actually from the Chicano language.
When you work with someone and they are staying late and you want them to go. But they still think there's too much to do but they have things to do elsewhere. This is what you say to them on the way of the door.
Them " there's a bunch more to do but I have to go. Can you finish up and do this... and this....?"
The girl will like you if she's known you for a decent amount of time and can't help but smile whenever your near. You may think she doesn't like you because she denied it once but in reality she was too embarrassed to say the truth. She will look at you any chance she gets and loves when you make her laugh. Girls like if you defend them and talk to them even if it's just to ask them for a spare pen. The smallest things matter. Shoot your shot or hint to her.
