As a french person i can confirm french waiters and waitresses pour burning hot coffee into their mouths like it's no problem and force it down their customers' throat by french kissing them

"Shared Drink" is the best tag I could think of for this, though that's usually two people drinking out of something such as a cup and using two straws. So I'm not if there's a better tag for it.
