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. In Single Stamina, Barney explains why he and his brother James suit up; "to distinguish ourselves from the millions of T-shirt and jeans lemmings out there". In Girls Versus Suits, Barney performs a musical number detailing his love for suits and suiting up.
Barney mentions Suiting Up on many occasions, and is frequently frustrated by Ted's reluctance to ever Suit Up with him (although, on rare occasions, such as the Pilot and Moving Day, Ted does Suit Up at Barney's request).
