- ISIS (people are doing this, don’t)
- Ebola (people are also really doing this, again don’t)
- Any sort of legitimate tragedy (do not be that girl that dressed as a Boston Marathon bombing suspect)
- Sexy Indian princesses
- Geisha
- Mexican sombrero dude

- basically anything racially or culturally insensitive. if you have to think about it, don’t do it
Seriously, have fun without being an asshole.
