A tricky person with an exterior that seems opening and inviting but when furthering a relationship with, becomes extremely scared to commit. A Collin is known for a wild attitude and is very witty, funny, and down right weird at times. Collin's are entertaining to large audiences and have a natural knack at being good with musical instruments and often sports. Collins tend to be horrible with relationships and are known for blowing it with the girls of their dreams.
