Meaning

From a marketing account title image: "When a girl sends 'morning', idiots reply 'morning', high-EQ people use '3 replies' to make her swoon!" The intent was to get people to click to see what 3 replies. But a straight guy literally replied "3 replies". His girlfriend happened to have seen this title too, and either being equally dumb or sarcastic, replied "swooned". So "3 replies" and "swooned" now carry sarcastic meanings.
