Mike (uncomfortably): "Ian, why are you holding me."
Ian: "Bro Grab, man."
Mike (suddenly comfortable and unmolestedly): "Ah. Cool."
"I pulled up to the curb with manly, Kate Moss confidence. And there's the dean and his wife, bulging with impatient fluids. I moved in for a bro grab and got totally whiffed" - Professor (ep. 'Late Date')
