the signs as i understand them from tumblr (and personal experience)

Aries: slightly scary, they could take over the world with their anger
Taurus: sensible, great friends
Gemini: smiley on the outside but a mess inside
Cancer: made of emotions and love, either the most observant person or the most oblivious no in between
Leo: glowing, personality is basically uptown funk
Virgo: no chill
Libra: say a lot and sometimes it seems pointless but they put meaning into everything they do
Scorpio: misunderstood, made of fluff inside i promise
Sagittarius: too many thoughts, probably have weird dreams
Capricorn: flawless in their own fucked up way
Aquarius: kinda weird but they always find a way to make it work for them
Pisces: sensitive but more intimidating than they are at first glance
