what do you call a unibrow? I have some faint hair between my eyebrows but unless you are close you wouldn't notice it. I only had one rude guy say Ihad a unibrow. he also said I had a hittler stash because I had a normal mustash but it wasn't styled anything like hittler's was.
anyway sorry for wasting your time with that little rant. :P
I would say they're just scared to wax their eyebrow. One time I was dating a guy who had the whole.. shaggy hair over his eyes style. One day he flipped his bangs up and said "peek-a-boo" and had a massive unibrow. OH MY GOD!! LOL. I asked why he didn't take care of it and he stated he was just scared of the waxing pain.
