1) Clowns. They're so creepy.
2) Needles. The kind for shots, not for tattoos.
3) Salt. I imagine having salt poured on our tongue in a pile and that image makes me want to vomit.
4) Some chenille blankets/scarves/socks. Heebee-geebees. *Shudder*
5) Cough Medicine. It's like I'm 5, I hate it that much. The taste makes me want to throw-up.
