Top definition
When your hairline looks awful or ghastly.
This may even cause others who see it to have a nauseating effect due to witnessing such an atrocity.
Drew aka Drewbacca perfectly exemplifies this definition:
His hairline resembles a staircase, now this wasn't done on purpose hence the "Fucked Up Hairline"
