Berlin surprise

The act of organising a birthday party for someone on a WhatsApp group that they are on. To both maintain an air of semi-secrecy and still respect the birthday haver’s wish of no surprise party, messages are typed and sent ‘quietly’.

Griff: ok guys, next Wednesday it is
Meg: Thilo is on the group though so we all have to type quietly

Gabe: ah, a good ole’ Berlin surprise
