(v) when one man anally fists another. This is a neologism, like "Santorum," inspired by the CEO of the pasta company, Guido Barrilla, making anti-gay comments. To quote Patton Oswalt, "Fuck the boycott. Do some real damage; from this point on, the slang term for a man-to-man fisting is a "barilla.""
I'm never going to barilla my boyfriend again; you wouldn't believe the santorum he can produce.
