Stands for "Get Amongst it". Is a relatively recent fad used by Australian medical student societies to try and get their fellow students interested in going to events and involved in activities. Unfortunately for them the majority of students find this acronym cliquey and lame.
"Yeh just GAI!" (gee-ay-eye)
::rolleyes:: "Get amongst what? It? WTF is it?"
A classic football team from Gothenburg, Sweden. They're known for their odd tendency to play qualifying-matches for different divisions almost every year.
A song popular among the fans of GAIS: "The year before the next one was the last year in divison 2 Ay, Ay the last in divison 2 ay the last in divison 2" And then we went straight through the first divison ay ay..." and so on.
