Get the Legasm mug.
Pronounced Le-gas-mic

On the 7th of February 2012 legasmic was founded at work by three nameless figures in Australia NSW approximately 1 hour and 30 minutes south of Sydney.

The word was derived from two words forged together to crate a word suitable enough to describe the best, most amazing of a certain thing.
