A condition where failure to maintain proper eyebrow grooming habits causes mutations in the eyebrow DNA. The two brows migrate toward the center of the forehead and elope into a single mass of intertwined brow hair, kind of like a mustache for your forehead. This condition is often found on homoerectus judias and eastern european gypsies.
