Ping Pong Gaylord

A series of sms exchanges.

German: P pg

Dude with black cap: Wat the hell did u send me?

German: What did i send u gayboy

Dude with black cap: U sent me 'P pg' msg.

German: O pingpong gaylord

Is it because reservist training is coming and now all my NS friends started to miss me and send me messages, including weird ones?
