we used to play "stop dicking about with your phone"
it was a great game, if someone was found to be dicking about with their phone, in a manner which was not to contact someone or organise something that we all gained something from, it would be removed from their possession and placed in their pint.

This successfully got rid of a few 'friends' I had collected and also proved to make conversations and debates in pubs more open to everyone.

Dropping it in their pint is a bit much,
what's more fun is if someone keeps getting texts, steal their phone when they get a message and reply something completely inappropriate.

it had become part of a tradition when someone spent the whole evening playing snake on their phone
the antisocial prat.

I have seen this done
although there wasn't a drining game involved, it was just a 'jape'
