Scab-Licker

I was sitting at a lunch table, just minding my own business, eating potato chips. I looked up and saw a first grader picking at a big scab on his arm--pick, pick, pick--and then he gave it a quick lick. I'm not actually saying that he is a scab-licker, but he might be.

The worst part was I couldn't eat any more of my chips. They looked too much like scabs.
