AD

AD is an abbreviation for "act dumb", this is when someone tries to act like he/she does not know what it going on despite the fact that they know well what is really happening. This is common among dumbasses who try to look cool and act gullible and dumb around girls

AD

Anno Domini, Latin for "in the year of our lord". AD marks the years after the birth of Jesus Christ.

For politically correct reasons, AD is being replaced by CE.

The year right now is 2004 CE! I mean... AD... freakin' Christians and their weird year systems!

AD

Short for the too short-lived show Arrested Development formerly on Fox.

Did you see the scene on AD last night when Tobias was dressed as a giant mole attacking a small model city and George Michael showed up with the jetpack? That was classic.
