A lack of definition in the glutular region, commonly seen as an almost imperceptible transition between butt and thigh. Often the butt and thigh may appear to be a single, amorphous shape. (pronounced buh-thigh)
Every time Kaitlin "accidentally" changes in front of me, I am lucky enough to see what a buthigh looks like unhindered.
