Having Your Bumps Felt means: Source: Medieval times. Healers felt lumps bumps on the scull to determine the disease. The largest lumps and bumps likely meant that the person was delirious, and it didn’t make sense. The term “having your bumps felt” is often used to refer to an answer or comment made by a person or situation in which the subject is very bizarre or ridiculous or silly.
