You obviously dot play enough video games. If google held no answers I'll explain real quick. "glass cannon" or the term "glass" in general means you build full damage (in the case of glass cannon) or full utility or something else, usually damage. The most defining feature about it is that you get no health/defense, so usually, later on in the game, everything can 1 shot you. Generally full glass build require the most skill as you die instantly if you even get hit... But you do absurd amounts of damage
