Unless you can look in the mirror and confidently say "I'm ugly," more than likely you're average. Everyone has their days where they feel ugly but if you CONSTANTLY feel this way, you're ugly. If not, you're average. And you'll know if you're handsome gang as well.
But the thing is, even the one's that consider themselves "attractive/handsome gang" and "ugly gang" are more than likely average. Some people are considered ugly or handsome universally though.
