an australian term or defininition meaning best friends, lets help each other out anytime, all the time, bros before hoes kinda shieet, not many ppl know this meaning, cos its special like-ED, and its cooler than most ppl think, no need for special handshakes, or slaps, its a seventh sense, cos seven is lucky like that! u know ur there for each other, esp trying to get him/her a gf/bf, u do what it takes, its like playing for the championship. gronk is the new word, should only be used sparingly, and on very rare special once in a lifetime friendships.
