Gleep is a gooey sometime unseen substance of unknown origin. It is anything that can be contracted from anything else that can cause a triggered reaction of disgust just by it touching you or being in contact with it. Gleep can stick to any surface, including but not limited to
skin. If you see gleep it is best not to mess with it because it
may become
stuck to you. It is passed by human and
animal contact, or by direct contact with it. Once someone catches the gleep, it can be passed from them to someone or something else.
I once
saw a guy get the gleep from his
refrigerator. He didn't clean it out for weeks and when he did he got gleep all over him. Then he pet his dog and it got on the dog too.
Now the dog is passing the gleep around.
