Sean is perplexed about a line in a Merle Haggard song

Sean is perplexed about a line in a Merle Haggard song and asks his listeners for help. Mama prayed my crops would fail – “why would a mother say that? I just don’t understand it!”
A listener rings in…“It’s because she wanted him to change his wild ways. If his crops failed, he’d have no money to go on the tear! He was a bold boy.”
Sean ponders the fact that no-one says ‘bold’ anymore, and wonders if little girls were called ‘bold’ too or were there just ‘bold boys’?
