matty ice can be a nickname for boys named Matt or Matthew, but boys with this nickname are pretty goated and they are normally really nice, but when he is mad he is going too mad and does not care much about what you have to say, he will trust you if you are close with him and he is hard to choice(doesn't know what to say or do is confused)
but guys with this nickname you will be lucky to be friends or more than that with him.
