In this context, it's typically used to catch people up on life events they might have missed on your social media. For example, you might text: “ICYMI, we got a new dog in the house.” In this situation, you could also use “ICYDK,” which stands for “in case you didn't know.”
ICWYDT is also commonly mistaken for ISWYDT (which means 'I see what you did there') because of 'text language' and 'internet slang' using the letter 'C' as the word 'see.'
ICWYDT means "I 'see' what you did there."
'I see what you did there' is commonly used as a sarcastic response, as it is a clever turn of phrase.
Person 1: Ahhh, I remember back in the day... when it was morning.
Person 2: Ha. ICWYDT.
