Grab your balls very tightly so that they squeeze together forming the image of....a brain. Then show it to another straight male and call him a fag and kick him in the ass twice.
Male 1: (pulls out testicals and squeezes them together) "hey Male 2, look over here."
Male 2: (looks) "AWWW DUDE!!!"
Male 1: "THE BRAINS!!!! OMG you are such a FAG!! BEND OVER."
