President Bangs is a phenomenon in which a female's long sidesweep bangs, due to an unfavorable condition, (ie humidity, sweat, rain, etc) begin to curl where her hair meets her scalp. This results in an aesthetic effect resembling the wigs of our founding fathers. To most ladies, this is undesirable and avoided at all costs.
I had to walk to school in the rain today and I can't brush my hair. I guess today I'll have to live with president bangs.
