What Are The Common Cheating Spouse Text Message Codes?

I’ve noticed some strange abbreviations and codes popping up in my spouse’s text messages lately, like “GYPO,” “143,” or even emoji combinations that don’t make sense in context - could these be common cheating spouse text message codes used to hide affairs? What are the most frequently reported ones, such as acronyms for hookups, secret meetups, or flirty signals, and how do cheaters typically use them to avoid detection? Can anyone share real examples from monitoring apps or personal experiences to help decode what might be going on?
