Suit Up! is a phrase regularly spoken by Barney Stinson. It refers to his policy of wearing a suit for almost every occasion. The origin of the phrase and Barney's suiting up is explained in Game Night. After his break up with Shannon, Barney found a suit store flyer bearing the slogan "Suit Up!". Feeling depressed, he took the flyer's advice (and the advice given to him earlier by the man who stole Shannon from him) and suited up for the first time, creating the Barney we know today.
