I think it's 1/11th of the original size.
(44100*2*2*8 / 128000 = 11.025)

No, you're not a freak, I use even bigger bitrates, around
~300-320kbps (something like -q8.6). I use RC2 Garf tuned 2 (-b350),
because, in my tests, it is still better then -q9.0 when it comes to
pre-echo, which is the only artifact you're going to encounter at bitrates
above 256kbps. The quality is great, and the filesize is still ~3 times smaller
then lossless...
