Students can train on how to use slang, watching Mexican shows, listening to local music, and following on social media producers that use slang in their everyday life. Casual talking with native speakers, playing in language exchange groups, or video gaming communities also come in handy. Retention is enhanced by maintaining a short list of new slang words and putting them in their context. It is all about exposure and practice, repeating the words used, and paying attention to the way they are applied as well as using them in similar situations when you are relaxed.
