I'm not sure if this has been seen but there's a lot of YouTube videos from BBC Radio 1 that shows two people playing a game known as "Innuendo Bingo". They do it while holding a mouth full of water and try not to spit out the water as the host is reading some stuff which I assume contains some form of funny innuendo. Most of the times they end of spraying it on each other.

There's a lot of girls who do this too, and they usually get soaked at the end.
