Bio Tat..

So my sister is trying to get another tat done...and this particular tat she wants it in a place....well lets just say that only few will be able to see lol. She really wanted something to describe her "pixie dust" if u will so I suggested a biohazard sign. I mean what a better warning than a biohazard sign right? lol. I just didn't want a typical biohazard sign so I added sum text that would help her get her message across. Problem is, is that I'm stuck between which word I should use for the tat and that's where u lovely people come in! So leave a comment on what u think and which tat do u think is best! ^_^
