Hatrick Sprayze is the act of vomiting thrice in one evening of drinking. If one has completed such an act then that person is also known as Hatrick Sprayze.
Sebastiaan: Did you hear that Medzhnun vomited three times on Friday after drinking at the Christmas markets?
Blaise: Yeah he's a real Hatrick Sprayze. After the markets we went to a couple bars. He puked once at the first bar, once at the second, and a third time on the walk home.
Edmund Hetrick's alter ego "Eddie Hatrick". Deriving from the hockey term "hat trick", Eddie Hatrick is famously known for boning down three different not-so-lovely ladies on consecutive nights. All three sessions usually performed without the "hat".
