to show how excited you are by what someone had texted to you..using exclamation points and/or smiley faces
the hottest fucking girl texted me how much she wants me to fuck her,so i texted back "fuck yeah,bro!!!!" with textcitement
Quite literally, excitement so grand it can even be sensed through a text message.
Person 1: "We're gonna have a kickass time next weekend!"
Person 2: "Yeaaaaaaaaa!"
Person 1: "Dude, that was some intense textcitement."
