You start off by giving your dago friend a nice juicy cleveland steamer on his chest. At the same time you must be fucking Ben in the ass at which point you remove your cock and place the tip of your dick right above his lip to leave a shit mustache. You then procede to dip your balls in the shit left over from your cleveland steamer and place them directly on the wop's eyes to leave the appearance of 2 black (brown) eyes. You then procede to get your dick sucked by a Sicilian and ultimately cum inside their nostrils once you're finished.
I was hanging out with a bunch of my Italian buddies until suddenly they asked me if I wanted to perform a Crundelman on them. It's apparantly a custom of friendship over there.
