However, it is not used literally to describe someone who bites calves. Instead, it is a derogatory term used to refer to:
* Someone who is annoying, bothersome, or clingy. The "biting" aspect refers to the person's persistence and unwillingness to leave you alone.
* Someone who is petty or mean-spirited. The "calf" aspect is a bit more ambiguous, but it might imply that the person is picking on someone weaker or smaller than themselves.
It's important to note that "Wadlbeisser" is a very informal and somewhat offensive term. It's not something you'd use in polite conversation.
