These verbs all mean to speak with pride, often excessive pride, about oneself or something related to oneself. Boast is the most general: "We confide [that is, have confidence] in our strength, without boasting of it; we respect that of others, without fearing it" (Thomas Jefferson).
Brag implies exaggerated claims and often an air of insolent superiority: He bragged about his grades. Crow stresses exultation and often loud rejoicing: No candidate should crow until the votes have been counted. Vaunt suggests ostentatiousness and lofty extravagance of expression: "He did not vaunt of his new dignity, but I understood he was highly pleased with it" (James Boswell).
