Return to Sender. What you reply when someone sends you a text message and you don't want to hear anything the sender has to say.
Tom just got a text message from his girl saying that she doesn't wanna be together anymore. He replied RTS and kept it moving.

Rock Tit's, When a girls nipples are so hard you can see them through her shirt. Often happens in the cold or if a girl has more pokey nipples and doesnt wear a bra. May even happen during erousal of a woman. Many guys get RT's too in cold.

RT's is short for Retard Tingles, or the sensation one gets after watching something painfully embarrassing and stupid. This type of feeling usually follows incredibly dumb commercials, music videos, embarrassing home movies, or Animal Planet.
"Ew, man, a Fitness Made Simple commercial."
"RT's dude, RT's."

RTS: Restless Texting Syndrome

When an anxious texter sends a second message after his/her first message has not been responded to for an extended period of time.

The message is different from his/her first text message and is done in an attempt to extend the conversation for fear that his/her previous message was viewed as a conversation ender.

Feelings of anxiety, restiveness and rejection are often felt before the syndrome yields its first "restless text "
Jessica: omg this kid wont stop texting me, I didn't respond to his last text and now hes sent 3 more trying to start a new convo

Jennifer: Classic RTS

'Right This Second'
as in...
'Give me 3 tacos & a million dollars RTS & I'll tell *so&so* exactly what everything thinks of her but is too chicken to say.'

or...
'I'm not 100% sure if I need vodka or a hug or 12 hours uninterrupted sleep, but RTS, I'd entertain any of them!
