The abbreviation PLAMS is commonly used among teenagers who want to share something with their friends without alerting their parents or anyone else who might be looking at their phone screen. PLAMS stands for Parents Looking At My 
Screen. It is typically used in situations where the sender wants to share something that they feel would be inappropriate or embarrassing if seen by someone else.
