Definition

A professor notorious for their exceptionally difficult courses and low grade distributions, typically wielding failure rates like a badge of honor. These academic gatekeepers often pride themselves on maintaining 'standards' while students strategically avoid their sections.

Example Usage

Don't take Organic Chemistry with Dr. Martinez—she's an iron prof who failed 40% of the class last semester.

Origin

Derived from 'iron fist,' referring to harsh, unyielding discipline

Fun Fact

Some institutions have informally tracked 'iron prof' ratings, finding that while these professors fail more students, long-term retention of material isn't necessarily higher.
