Pootantov
A person who does not man up to a task or a job asked of them. A man acting girly or scared. A pansy.
You tell your friend to throw a snowball at the next car that passes (as your doing it..). He sais no, he is scared, and he doesnt want to get caught or in trouble. You would say stop being a pootantov. (similar to stop being a pansy)
