An amusing and, yes, silly name for a fairly obscure sub-genre of independent music which can nonetheless be quite descriptive and quite useful in terms of making connections between particular bands (this is how I find new music these days - by following pointers from band to band..."If you like X you might be into Y, they have a kind of math rock thing going"). A fun phrase when used tongue-in-cheek - try also "these guys are totally mathy."
You have to have a sense of humour about these things.
In trying to justify the use of a term like math rock, I would point out that mathematics can be seen as being concerned primarily with structure, in particular complex structures. Similarly, with bands labelled as math rock, there is an emphasis on composition, on musical structure, in particular the creation of complex and/or unusual song structures, progressions, dynamics, melodies etc. Math rock can also involve sudden or multiple time changes, tight performance, multiple layers of rhythm (be prepared to experience the drumkit as an instrument in its own right - making and time rather than just keeping it) and melody, experiments with tonality, dissonance etc. The "rock" bit is due to the fact that good math rock, while being 'clever', can still kick you onto your ass with its energy.
Math rock is often purely instrumental, lyrics viewed as an unnecessary distraction from the music. If you want words, go read some poetry.
Following are some bands I would characterise as definitively math rock, and some which just seem appropriate to mention in this context:
All these bands are excellent and many have web pages with MP3s available. Try http://www.southern.com/southern/ for starters.
I have noticed a trend within math rock type bands which involves giving songs elaborate, convoluted, weird, smartass and long names, possibly as a means of textual output otherwise deprived due to the absence of lyrics. Examples follow.
