The high school teachers said the song, "Relativ" by a cappella group Wise Guys, was included in the listening comprehension portion of the national exam for 16 and 17-year-old students taking German, Stuff.co.nz reported Wednesday.
"I assume there's a lot I could do with you in bed," the group sings in the tune.
Teachers and some students described the song choice as inappropriate for an educational setting.
Natasha Smith, head of German for Christchurch Girls' High School, said the song was not only inappropriate, it was also difficult to understand even for seasoned German speakers.
She said the song is filled with ''colloquial expressions, metaphoric language and a myriad of other items, even nonsensical items like 'Eg ich mag dich relativ sehr' -- 'I like you relatively very.'"
''Songs have a place in the classroom, where you have time and in this case a dictionary nearby for the students. However, to use it in an exam is completely unacceptable and simply unfair,'' she said.
