“Merch” in text usually means merchandise, but in online slang it can also mean “I swear” or “I’m serious.” People often use it in chats to show they are telling the truth or emphasizing something strongly.
You might see the word “merch” in TikTok comments, Snapchat chats, Instagram messages, or casual texting. Sometimes it refers to products like clothing from a creator, while other times it works like a slang expression meaning “I’m not lying.”
Because the internet moves fast, the same word can have two different meanings depending on context. That’s why many people search for the phrase after seeing it in a message.
