YOU.
A very simple way to tag (text etc.) Someone one simple word that means you are thinking of them. ONLY them.

like you calling them out saying like..."you know why I'm reaching out, because it's all about you right now." kind of thing...your on my mind. Letting them know they are priority, no matter where you are or what you are doing. In a positive flirty way. Calling someone out to let them know what's up without saying it.

Texting a single word letting them (YOU.) KNOW how much your thinking of them and nothing else... STRONG
YOU.

(sent by text as one word to your boyfriend while your out w friends.)
I texted him, I just said "YOU." and he called right back!
