Get the isac my brother mug.
The moment when you question your brother's gay nude magazines, constant man friends that sleep over, and his feminine choice in movies and other interests and realize that your own brother is a flaming homosexual. May occur early or extremely delayed from the point your brother starts to become a homosexual. Is usually a moment of epiphany.

My brother's keeper?

(Nino walks closer to Gee, then reaches in Gee's coat to find and take his glass dick/crack pipe to confront him)

Was it this......glass......dick...you've been sucking on, huh? Huh? Was that it? Now I see how you let that motherfucker infiltrate. He used you, Gee.

(then Nino throws Gee's glass dick/crack pipe very far from where they're standing)
