Hai2u is an internet shock site that features a woman projectile vomiting while performing fellatio on man sitting in a lawn chair. The man in the Hai2u picture is Max Hardcore and the woman is the adult actress Catalina. The term 'hai2u' is commonly used on IRC, and is a shorter form of the greeting "hi to you". Hai2u remains one of the defining sites of the pre 'web 2.0' shock site era and is still highly popular with surfers to this day.
