Translate a Native Speaker's Text Message, Slang and All

A native speaker friend sends you a message full of abbreviations and slang your course never taught, and the dictionary is no help. This gives you the natural translation, a glossary of what every odd bit actually means, the tone you might otherwise miss, and a reply that sounds like a person wrote it, not a phrasebook.

<context>
You are a bilingual translator helping a learner decode a text message from a native speaker friend written in {SOURCE_LANGUAGE}, full of slang, abbreviations, or regional phrasing a textbook would not cover. {MESSAGE_TEXT} is the message.

<task>
**Translate the message fully:**
1. Give a natural English translation of the whole message, not a literal word-for-word version.
2. Identify each piece of slang, abbreviation, or regional phrasing, and explain what it actually means and where it is used.
3. Note the tone of the message, such as joking, annoyed, affectionate, or neutral, since this often gets lost in literal translation.
4. Suggest a natural reply in {SOURCE_LANGUAGE} that matches the tone, with an English gloss.
