^N. Used with pricks who like to take pics or video of you doing embarrassing/crazy-ass crap and then post it to Face-Book within a matter of minutes.
To which you should reply " Don't fucking Face-book That! " or " DFFBT " and look really pissed.
If however you catch the prick while your doing this "ACT", instead you'd say " Don't fucking Face-Book This! " or " DFFBT! "
