The act of shoving an umbrella up your arse, opening it up and filling your arse full of pineapple juice. Under my umbrella, ell a ell a ay ay ay.
Me and the Mrs were a bit adventurous last night, we tried out the dirty rhianna. Safe to say we won't be doing it again. I will not be under that umbrella anymore.
