Awkward and contrived personal flourishes in written communication as a sign-off. Typically used by douche bags as a signal of their self importance. Mainly found in emails, but also text messages, chat and old fashioned paper letters. Typically take the form of letters or symbols, but occasionally, as with The Artist Formerly Known as Prince, leverage wholly new iconography or imagery.
"Did you see Duane's email signature? "Ci@o" What the fuck is that at sign about. What a douche flourish."
