NEW YORK (CBSNewYork) — Should I wear a jacket?

I keep thinking today’s Tuesday.

Wanna split a cookie?

Mundane phrases like these capture the hilarious essence of everyday banter used by women – and thanks to the “S–t Girls Say” YouTube videos, the phrases and concept have become a pop culture sensation.

Since being released last December, the viral videos have racked up over 30 million views. The Twitter account continues to be a smash success, with 9,000 new followers a day. Now the two men behind the concept, Kyle Humphrey and Graydon Sheppard, have published a book based on the idea.

“Even before we made the videos, we thought it would make a great book,” Humphrey said.

Before it became a phenomenon, the idea came to the guys when they were just hanging out.

“We were sitting on the couch one day, and Graydon asked me to pass him a blanket, and that kind of struck us as a feminine thing to say or ask for,” Humphrey said. “So from there we just started compiling all these things that girl say.”

“Once you notice one thing it just starts popping out at you everywhere,” Sheppard said.
