"The name "Durinho" started when Gilbert and his brothers Herbert and Frederick started training at the Nova Uniao HQ in Rio de Janeiro, as teenagers. One of the team's main figures, Vitor Ribeiro used to jokingly call Gilbert's older brother "Todo-Duro", meaning "Hardman", a jest celebrating Frederick's tough-guy demeanor. Being a smaller version of his brother, the teammates started calling Gilbert "Durinho", a humorous way of saying hardman - as in "tiny tough guy"."
