fbackspace

(verb) - The act of erasing everything you are about to say on Facebook chat.

This causes the person at the other end to know you're about to say something, and that for them to say something would be like interrupting a face to face conversation.

Usually occurs when fblirting or heated conversation.

also fbackspacing

You're about to say, in an attempt to go on a first date;

"would you like to go and watch One Day with me?"

WHEN, all of a sudden you get cold feet,

fbackspace everything and say instead;

"so how's your brother doing"
