This song is sung by Gumball and Darwin after they take their father's supplements in the episode The Mustache.
We're gonna test drive a car, And say we need a little time to think about it - Because we're men!
We're gonna pay more for the movies, and chop down trees, and eat a lot of meat - Because we're men!
And we can have our own kids! ...but we're gonna wait until we meet the right person because it's an important decision. But in the meantime we can barbecue! Buy power tools! Get tattoos! Buy our own shooooes!
