'Glatt', which strictly speaking has no meaning outside meat, is now a catch-all phrase with sociological rather than halakhic significance. Has a technical meaning relating to the lungs of a slaughtered animal, denoting a lung "smooth" and without adhesions or growths. Also has an interesting variant - 'Glatt treif' - meaning the polar opposite of 'glatt kosher' -- i.e. unarguably, extremely non-kosher or unacceptable to Orthodox Jews.
