What is Plx?
1.
What noobs say when they cant be bothered or dont know how to say "please".
Note that plx doesnt have any vowels and also does not even 'sound' like it has vowels, like the word 'rhythm'. This means that plx actually isn't a true english word. So when people say this, you can actually ask them to speak in english. If they get confused, call them noobs.

Scenario 2:
You: talk english
Noob: k plz giv me hil thx
