You’re a catholic nerd if…
… you get momentarily confused when you hear the word “discernment” refering to something besides trying to determine God’s will.
…you know who St. Sharbel is, and are shocked that others don’t.
…you have a special place for all of your religious art overflow, since there are only so many images of the Virgin Mary one room can handle.
…you not only know what a motu proprio is, but you fantasize about ones you would issue if you were Pope (I would ban certain hymns and certain musical instruments in Mass)
…someone says George Weigel is coming to town and you say “cool.”
…your priest tells you not to mention the fact that he has to say 3 Masses in 1 day. This is double nerd points because a) you know why this is problematic, b) you stand out enough as a nerd that he knows you will know why this is something to keep on the lowdown. If you then go off and call the bishop and let him in on the secret, you should start a Catholic Fanatic blog
…you stereotype people by their apostolate, i.e. Opus Dei, Regnum Christi, etc.
…your most common phrase at parties starts with “Well, the Catholic Catechism says…”
…you gauge your movie pix based on their ratings: A-I, A-II, A-III, A-IV and O [Note: these are the ratings used by the USCCB]
…its not the unity candle but the renewal of your baptismal promises that you want to add to your wedding (if you see the unity candle at someone else’s wedding and say to yourself “oh, not as hard core as I thought,” then you are an uncharitable Catholic nerd.)
…you have a disturbing dream that a series of misprints in the breviary shatters your prayer life.
…when a friend asks you to stop by the Catholic bookstore and pick up a statue of St. Joseph, you ask “Do you want a nice one for your house, or one to bury upside down to sell a house?”
…you don’t feel right about eating a donut on Friday because its lent. You didn’t give up sweets or anything, but somehow that just doesn’t seem right.
…you stop and compare ashes with friends after Mass.
…you remember the names of the apostles by going through your brothers (yay big families!)
…you refer to having a bit too much to drink as, “not in the best state to evangelize.” (To which your friends reply, “meet 'em where they’re at, man!”)
…at a pre-Christmas party, you ask your friends if anyone will be “liturgically offended” if you light all four of the candles on the Advent wreath even though it is just Thursday of the 3rd week of Advent.
…your roommate tells you that you were talking about the pope in your sleep (this was a few years ago)
…“offer it up” is in your vocabulary (extra nerdiness if you add “for the good of the Mother Church”)
…you stay up all night reading various church documents instead of studying for finals, just so that you can prove that an accolyte is not an ordinary minister of the Eucharist. (this also proves that you a pretty *%#@ stubborn Catholic nerd)
…you have heard or taken part in a conversation along these lines-
“Do I smell like incense?”
“Yes, you do.”
“Good

”
…you compare a shower to confession…instead of confession to a shower (this analogy was how we discovered that we were truly Catholic nerds and began the list)
…you have nightmares about defending the faith from angry, liberal, Catholic women.
…you make a hobby of learning dead languages that have no use except liturgical (latin, OCS, ancient greek)
