To give someone a brief, pointed, reprimand via text for an "out of line" remark. The virtual equivalent to a "slap upside the head" for an inappropriate or rude comment while texting or in "chat" with someone. A "WTF were you thinking moment" where you give someone a quick "dressing down" in order to bring the conversation back onto previous path.
She deserved a chat slap for being so rude to her best friend. OR ... She gave him a chat slap when he answered her question about the homework assignment, with ribald sexting.
