On the topic of hand shakes. I can not stand when a man gives me the limp fish handshake. Don't get me wrong, I appreciate the fact that they don't try to break my fingers, but I definitely try to break their hand when they pull that.
Popsicle sticks, the wooden ones when you get to the end and you have to touch the wooden stick with your lips or tongue. That gives me goosebumps and makes me want to gag. It is just the texture of the wood. Yuck.
When my husband lets his mustache grow out to the point that it curls over his lips and he can put it in his mouth. Instant gag.
