2. The actual hands covered in the sticky substance
However, Jam Hands are known for their sharing. They like to mark their territory and think this is amazing, a gesture of unity. However, it is disgusting. Once you have observed a jam hands you will be quick to notice smears or other texturized traces that the Jam Hands leaves behind. You will learn the definition of repulsed.
Friends or observant people who are well aware of when a Jam Hands is in the room, tend to keep a 30 feet minimum distance from the Jam Hands at large and are quick to use public/personal hand sanitizer if available when an accidental/forced encounter with the jam hands or a certain surface that the Jam Hands has touched, has occurred.
Example: the kid from your third grade class, that smelt musky, who wore the same shirt every day for 2 weeks, that had 20 different types of chocolate stains on it, and would eat popsicles and the popsicle would melt onto his hands and then fabric fuzz would get stuck to the popsicle mess on his hands, and then he'd have yesterdays gravy on his face and it would be french kiss friday and people would dare you to kiss him and you would slightly vomit at the thought of it in your mouth, and the teacher would dump his desk on clean up monday and grilled cheese sandwiches from 2 months ago would fall out. Jam hands + Jam hands hoarding.
