After you write a letter and think that more needs to be said you add p.s. after the body of the letter, to address the rest of what needs to be said. The abrieviation means plus shit.
Dear Joe,

P's is a code word short for prostitutes. Derived in late 2010s-early 2020s by a couple dudes called Hasan and Asad. Useful term when you want to talk about your hooker experiences in public or around people so they don't know what you're talking about
Asad: daaled (had sex with) two p's last night in a 3some cuz
Hasan: Gowon lad were they fit
Asad: decent lookin' Czechos but they gave me a good time so I'm not complaining, only 100 bar aswell
{abbreviation of power shit};to take a shit that makes you drowsy;a shit so bad your stomach cramps up. Proper terminology to use in mixed company or an office environment.
