When guys are about to do something that could be portrayed as gay, they state beforehand "No Homo." This clears them both from being gay and being called gay.
Girls: "We will show you our tits and make out with each other if you two guys kiss."
Guys: "Let's do it. But first, No Homo."
Guys: "Let's do it. But first, No Homo."
