A breed of italian men that are so charming and good looking that women fall in love with them immediately. As soon as a woman sees a cassinis they will do what ever they have to do to have sexual intercourse with him. A cassinis is usually into kinky/dirty sex and enjoys skiing.
Man: that fucking cassinis stole my girl last night. I hate those damn cassinis guys, they always take home all the hot girls. i bet a cassinis always does ass to mouth, lucky bastard...
Girl: i found a cassinis last night. my friend and i brought him back to our place and let him do ass to mouth to both of us while my boyfriend watched and cried in the corner.
