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 

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."

Ted: Hey, you want to go grab a burger for lunch?

Ralph: Maybe, if I can finish this fuckin’ RTSS.

Ted: Man, that’s rough.

Ralph: Tell me about it. If I had known I’d be doing fucking taxes all day, I’d of just stayed home and sucked down a six.
