A foolishly naive or incompetent person.
Someone who lacks
education, experience and expertise, especially if they overestimate their own competence.
Someone whose behavior would elicit the
question, "are you new?"
The implication being that they have just been born, feet first, and they are still wearing their mother's
snapper as a hat.
"Did you hear about these dudebros who just
dropped $80k on a new website domain and think they'
re going to
rake in 8 figures in the first year, having done zero market research? What a pair of snapperheads."
