music teacher butt 

possibly the most elusive of all butt-shapes, music teacher butt can be described as unusually long and increasingly droopy toward the south end of the caboose. nearing maturity, MTB begins to resemble a second bosom. music teacher butt affects 1 in 3 music teachers in the United States and, interestingly enough, also occurs in 1 out of 30 female band members. to spot MTB in the wild is rare, and should therefore be deemed a special moment in one's life.

1) damn, she got that MTB! was that Mrs Denny?

2) i just got back from the obstetrician and she diagnosed me with music teacher butt. dammit!
