I am a total noob when it comes to working with Linux. The only experience I have with Unix is in college when I used to pipe the manual of trn via the write command to unsuspecting classmates. If I remember correctly, this is how you do it.
write username | man trn
This would fill the user’s screen with a bunch of text. Always good for a laugh.
Normally, the write command informs the receiver who originated the message. I remember there was some way to hide who I was when sending the message, but have since forgotten that trick. Yep, them...
