Partygoer: Man, you got any tonic water and limes?
Host: Nah man, just use Sprite.
Partygoer: What am I supposed to do with Sprite?
Host: Make a Poor Man's Gin and Tonic, fool.
Derived from the word "platonic," meaning "friendly," and also used as the opposite of romantic. "Play-tonic" is used to describe a "friends with benefits" situation. Their relationship is platonic, not romantic, but it also includes "play," or sensual/sexual interaction.
Person 1: Hey dude so are Mike and Jen just friends, or are they like a couple now?
Person 2: Neither, it's totally play-tonic.
