Noun. The most badass explorer to exist. Discovered America before Columbus and didn’t even have to pillage the natives to be remembered. Has a day named after him.
If dragons existed, Leif Erikson probably would have ridden one to California from Iceland and stopped global warming.

From the popular "Leif Erikson Day" Spongebob episode but meaning a cheap bottle of vodka; getting smashed and becoming very touchy with others; or hogging the limited and cheap alochol your group has
"I could only get some Leif Erikson for tonight's kickback"
"Jamie is completely smashed. She's in Leif Erikson mode."
"We only have half a handle of Smirnoff for tonight so no one Leif Erikson tonight."
