fishmouth
Lips parted, surprised
A fishmouth is an opening or gap that resembles a fish's mouth—wide at one point, tapering at the ends.
In sewing, a fishmouth is an unwanted gap where fabric pulls apart, especially at seams or buttonholes.
In plumbing and metalwork, a fishmouth is a curved cut at the end of a pipe allowing it to fit flush against another pipe at an angle.
The verb means to cut or shape in this way: fishmouth the tube before welding.
