1) A shower. Walk around in a towel and hold shampoo.
2) Hallmark. Buy five cards (of different sentiments) and attach them to your body.
3) A sex machine. Tape condoms to a fan and wear the whole thing as a hat.
4) Snack guy/girl. Buy a bunch of Doritos and hand them out at parties. It’s not a costume, but nobody will care because you’re giving out free Doritos.
5) A Greek life mixer. Walk around with Greek salad dressing and cranberry juice.
These are all viable options. If I see someone doing #4, I expect extra Doritos as a token of appreciation.
