A typo of the word "strong," originating from competitive play of a game of Heroes of Newerth. Mostly used sarcastically because of it being a mistype.
Port key pebbles is too stronk, GG.
One of lego's production lines started around 2000, bionicle was one of lego's success stories due to the series not letting lego go bankrupt after the age of video games beginning. It lasted for around a decade until the maker of bionicle made hero factory. Which old time bionicle fans still hate to this very day. The series will always be a legend and should never be forgotten.

jack: they're bionicles man.
tom: oh ok thats cool bro.
