An extremely good looking male who bears (what some men consider a gift) the curse of entrancing sexiness. He, without any effort, will make ANY woman fall in love with him. Whether the woman be a straight, lesbian, transgender, a crossdresser, or a man who desperatly longs for womanly parts, she (or he) will fall in love with the suave composure of a Sai. Beware when around this individual. You will lose your girlfriend/wife, sister, mother, aunt and even your grandmother. Sex is a Sai's greatest weapon even though he unknowingly wields it.
Damn he is a fucking Sai.
He just Sai'd my wife.
