The act of two males standing back to back with a dildo in eachothers assholes. Similar to scissoring but in a homosexual way. If u look closely it looks like a dumbbell ready to hold by the handle and lift up over ur head and rip those gays a new one.
Today I saw my daddy and my other daddy doing the dumbbell in my bedroom with my sissy dildo.
