He was thinking that HE wants a dagger that happends to come out looking like a cock lol.
I doubt lesnar gives a flying fuck what anyone thinks of it though.
Scenario, Brock takes a hot blond home, things get hot and heavy, he takes off his shirt, she asks, "Why do you have a a big black cock on your chest?"
"It's not a cock it's a knife..."
Girl: "You're not one of those...bisexual voyeur types are you...?"
"No, it's a knife, not a big dick..."
"Are you, what's it called... projecting, yeah, that's it, projecting what you really want, yet you're ashamed? I saw that on Oprah."
Now the mood is lost, and the girl gone.
