Noun. A pun on "Adam's apple," it refers to the large bulge on the trachea when it occurs on a woman. (Note: this may be the sign of a male-to-female transvestite or transsexual, or may simply be the luck of genetics).
"Holy crap! Look at that madam's apple on Ann Coulter!"
Noun, plural in construction but singular in usage. Originates from the acronym "Board Of Cooperative Educational Services," (or something similar), a 'special education' system often used to educate mentally-retarded people (frequently children, but occasionally brain-damage victims) as much as one possibly could, which, typically, isn't much. The acronym eventually became a term to describe any person so enrolled in one of these systems, and through logical extension, a an insult to suggest that they are as intelligent and mentally competent as a person enrolled in a BOCES system.
"Jim is such as boces, he can't even turn on the computer correctly."
"Our teacher is a real BOCES. It took him 20 minutes to get the VCR running."
