offwidth

AWF-width
A crack too wide for fist jams but too narrow for the whole body to enter. The most dreaded size in crack climbing — nothing fits well, everything is strenuous, and progress is ugly. Offwidths demand awkward, grunting techniques.
Etymology
Climber slang. “Off” in the sense of wrong, ill-fitting — the width is off, meaning it doesn’t match any comfortable part of the human body.
