Shiva Stacking 

In the popular zombie-horror first person shooter video game Left 4 Dead, survivors oftentimes employ a tactic knows as Shiva Stacking/Survivor Stacking, where all the survivors crowd into a corner and begin melee spamming.

This tactic is known as Shiva Stacking because of all the arms/rifle buttstocks protruding from what oftentimes appears to be one body mass.

The only way to trump survivors who are Shiva Stacking is to introduce a Tank.

The Survivors were Shiva Stacking in a corner during the Death Toll Finale, and not one of us could get a pounce on them or nothing.

clan stacking 

Clan stacking is a situation in online team gaming where one team consists of players that are part of one or multiple clans while the other team consist of random players(PuG). The players that are part of a clan will usually dominate the players that aren't because they can coordinate and communicate. Clan stacking if frowned upon because the majority of online players don't belong to a clan. Some games/servers prevent clan stacking by spreading the clan players out over the teams.

Our team is being dominated by a clan stacking team in BF4.
