 * Flash Farming : A style of farming when you farm your lane creeps until the enemy tower and then proceed to clear neutral creep camps in quick and efficient rotations. This is often the fastest method of farming, but it also allows the enemy to farm your creeps freely by their tower and can be risky, as being near the enemy tower is often an easy gank, or the enemy might know exactly where you are clearing the camp closest to the lane tanking creeps and losing health, etc.

The classic flash farming ability is Shadow Fiend's Shadowraze which allows him to mow down wave after wave of creeps with ease.

Some new players get it wrong and think it means "Finish Fast", commonly mentioned when one team is being overwhelmed quickly, easily, and frequently by the enemy team, wanting the game to end as soon as possible.

 * Fortification : The Glyph of Fortification is the button in the bottom right hand of the screen that renders all allied buildings invulnerable for 5 seconds on a 5 minute cooldown.
