[@olcharlieboi] Then prove to me your definition of bio is a correct one. Because I'm sure as hell not finding it.

What you're describing is a [s][i]profile[/i][/s]. EDIT: And here I go misusing it myself. Profile is description of a person, damnit. I'm very strict when it comes to definitions of words, and always edit something out when I find I've misused one.

Also, I listed a weakness. They're not very effective against soft material. But if you want me to list that, I will. 

EDIT: Added in the sound detail.

EDIT2: Also, Bio means 'Life'. Biology is 'Study of life' and Biography is 'Describing life'. None of those are about likes or dislikes.
