In spanish it literally means pork rinds with milk. The disgusting sound to it makes people crinkle their nose. It is used to describe a weird, random, or awkward person or situation like the literal meaning.

Because it sounds so strange, people use it randomly to break the boredom or awkwardness in a conversation. Most of the time it is used when the other user replys just "LOL" because everyone knows that means they are bored of you.
LOL, her hair is like chicharonez con leche!

Guy: I'm making a sandwich.
Girl: lol
Guy: Chicharonez con leche
Girl: LMAO what's that? XD
