This is when a character reveals that she or he was educated in (or is being educated in) a field or subject that is unexpected for the character. Typically, this gag takes the form of a college minor, as per the title suggests.
For example, a tough macho man could minor in Women's Studies or a ditzy society girl is minoring in Particle Physics.
A great, if narratively cheap, way to showcase Hidden Depths. It may come up at a plot relevant moment and not just as small talk. In such a situation this can act as a justification for a Deus ex Machina or Ass Pull (possibly softening the blow). Sub-Trope of Suddenly Always Knew That. Compare Subject 101. Minored in Ass-Kicking is when combat ability is the character's secondary but notable asset. Compare and contrast Expert in Underwater Basket Weaving, where the character's expertise is portrayed as completely useless.
