look up any word, like fleek:
Short for "please", used in email by lazy asshats who put the minimum possible effort into being polite. Usually used in messges demanding something that's trivial for them but a PITA for you.
To all staff: Pls make sure your T.P.S. reports have the proper covers.

Parking Lot Syndrome. When a group of friends stand around in the parking lot talking and chatting after dinner, a movie, or an event. This usually occurs when deciding on what to do next and can last a few minutes. However, it's only considered PLS if it lasts a considerable amount of time.
"Let's get rid of this PLS and decide where to go already! We've been out here in this parking lot for an hour and I wanna do something!"

more specifically, it's used as an appeal.

example 2: you think you can hook up with that girl? pls.
