You...

- aim to improve the signal to noise ratio on the Internet. For example, you know what a TED talk is ... and like them.
- learned a non-existent language.
- made polyhedra out of food.
- sung a song with lyrics of chemicals/protein names.
- memorized all the countries of the world ... not because you had to.
- collected one of every state's quarters.
- created papercraft/cross stitch/perler beads to anything show/game/book related.
- were part of band camp/chess/debate club.
- attended a scifi/medieval/steampunk/anime convention to see all the merchandise and people dressed up.
- know that C++ is not a passing report card grade.
- could be a recreational mathemusician!
- find Ferengi bar owners strangely charming (or even if you don't, but you actually get this reference).
- have nostalgia for certain catchy Ocarina-based melodies.
- naturally think "data dog" when you see a Welsh Corgi.
- like pumpkin sqrt(sum(1/n^2, n=1..inf)*6).
- hear IPA and think of something linguistic, rather than beer.
- you're a lean caucasian girl (particularly fond of reddish hair, freckles, and green/blue/amber eyes, but these are just icing).

Answers:

- C++ is slightly less than a B- (؟), or, if you write computer programs, a typical language of choice for most serious graphics and gaming.
- Charm and Strange and types of quarks, subatomic particles.
- The ocarina (looks like a fat flute) is used in a favorite game of mine (Zelda: Ocarina of Time) to transport yourself and activate various triggers. I doubt most girls have played it, but those who do, seem to like it just as much the guys - to the seriousness of getting tattoos from a prominent symbol in the game.
- The Welsh Corgi in the animated series Cowboy Bebop was a 'data dog', or an organic courier of information.
- This infinite series forms the familiar sequence 3.14159... (alas, this is really the only one I remember anymore, but it's still neat the sums of ratios eventually to converge to something)
- IPA, in the linguistic domain, stands for the International Phonetic Association. The IPA alphabet is a collection of Latin-like symbols that have a direct correspondence to actual phonetic sounds (none of this 'c' sometimes sounds like 'k' but other times like 's' crap).
