P! 

Appearing in the anime FLCL OVA on the front of Haru Haruko's (caricature) yellow vespa, a white letter "P" and exclamation point encircled in black is widely accepted as a logo representing the Japanese rock group "The Pillows."

Was it created by the animators as spontaneous endorsement? Is it an infamously old band logo resurfaced? Originally some confused representation of Piaggio-Vespa? probably the most former, everyone seems to be going with it.

While not popularly recognized in it's own country, "P!" seems to have a runaway success story in the United States due to the promotion of American anime and J-rock fans alike- the result being that FLCL, The Pillows and the "P!" logo seem to carry a synonyms relationship.

P!

Pass it on, because nobody seems to be complaining about it.

P! 

The symbol on Haruko's Vespa from the anime FLCL. Rumors speculate that this is a P for "The Pillows" while others say that it is a P for Piaggio, the manufacturer of the Vespa scooter.

Nobody knows for sure.

/p 

means "platonically". Like "/s" it's commonly used at the end of a phrase to denote that the message is entirely platonic.

Crush: HAPPY BIRTHDAY!!!! I LOVE YOU SO MUCH!!/p
Me: haha thnx *kinda heartbroken inside*

/p is a tone indicator which means 'platonic'. it's used in text to show that whatever you're saying, is completely platonic, unlike its counterpart /r

"I love you bro! /p"

"You're so pretty /p"
