NW 79th Street in Miami is a street where ghetto hoes do the walk and turn their tricks. Basically it's an insult meaning your mom is a whore.

Jefferson: "Oh yeah? Well, I saw yo momma on 79th Street last night!!!"
Willie: "Shit motherfucka, don't talk about my momma."

Tastes so good, make you wanna slap yo momma 

When you try some new food that tastes so delicious it makes you wonder "why can't my mom cook this well?". This thought makes you so angry that you feel like slapping your mom for feeding you mediocre food.

Of course, this is usually meant as a joke or figure of speech. Most people love their mothers and would never do such a thing.

Kid 1: Yo dawg, I'm tired of eatin' at home. My momma feeds me the same ol' grilled cheese sandwich for lunch every-damn-day.

Kid 2: Don't sweat it home slice. Why don't you come on over to ma crib after school? I'll make you to best PB & J sandwich you've eva tasted. Tastes so good, make you wanna slap yo momma!

Kid 1: Yeaaah boii!!

Seems to mean that you've done bad, when you hear this it is likely from the mouth of a very ghetto woman. Regardless of whether or not you can tell the gender of the creature, run. If you are within grabbing distance, Run faster.

They can smell fear.

Ghetto chick(?): "Im funna beat some niggas face on yo mommas ass!"

You: "I'm soooorrrryyy!" (crying)

Ghetto chick beats you down.
