It's called The Tinder Games (like The Hunger Games, get it?). Hungry girls find thirsty guys on Tinder and just ask them for pizza and sushi. And the poor saps just do it, with or without the promise of a date. Guys, you're better than this. Shameful, man, just shameful.
Guys have been falling for this kind of thing for basically all of human history, but this just may be a new low. "Buy me a pizza" is the new "buy me a drink."
