When, in the course of a game of dota or another hero based, warcraft 3 map, you have a hero possessing an ability called chain lightning. Upon using this ability, on usually shouts "Berp Chain Lightning!!!" as loud as they can, so as to alert the rest of the house as to what just happened. Often most exuberantly used after the player using the ability has just KS'ed his team mate or friend.

Some say that the ability 'Arc Lightning,' found on the popular dota character named 'Zeus,' also constitutes the use of Berp Chain Lightning, as its animation and effect are similar. Although this is still widely debated among linguistics and dota players alike, both sides agree that it still is pretty cool.
