These are things that really gross me out:
~ Used tissues just lying around
~ The thought of any kind of sharp object penetrating the skin barrier (not the actual action, just the thought)
~ Puke
~ When a gross couple practically spoons in front of you (especially at church)
~ People who don't wash their hands after going to the bathroom
~ The texture of an overly ripe banana
~ When you're brushing your teeth and not all of the spit is ejected from your mouth so you have to suck it back into your mouth (once it's out of my body it becomes disgusting to me; also I almost threw up just writing this one down)
~ The thought of putting on previously worn underwear after you shower
~ Picking up a bug after you've killed it even if you're using a tissue
~ Putting on a boy's hat (especially if you can see the sweat marks on it)
~ Changing old people's diapers
~ The thought of using another person's toothbrush/deodorant
~ Saliva in general; whether it's coming from a baby or an animal, I just don't want it on me
