Knock me on Facebook? [closed]

When you have to ask someone to communicate with you through Facebook, how do you ask it? "Knock me on Facebook" is a familiar term in Bangladesh. But I don't know how much appropriate it is.

Solution 1:

I have to use Facebook often for my work.

I have not heard "Knock me on Facebook" in the US or Europe, but I like the expression!

I agree with the suggestion that "Contact me on Facebook" is probably the most precise and technically correct expression to use.

In the United States, I hear the following expressions often: 1) "Facebook me." 2) "Message me on Facebook". 3) "PM me on Facebook" or "Send me a PM on Facebook", where "PM" stands for "Private Message".

Solution 2:

In American English, we would say: Hit me up on Facebook.

Hit me up is slang for contact me.
