stacking the team 

In high school football when players from different school districts converge to one school to make the sports team better. They stack the teams with good players from other distriicts

You see the same high school football teams in the championship games because the coaches and parents are stacking the team with all the good players from neighboring school districts.

teamstacker

In FPS, but usually RTS:
Someone who puts all of the better players on his team, instead of distrubuiting them around evenly. This causes the entire game to be one sided, and generally unfun, even for the winning team, because there's really no challenge. Usually seen on Starcraft from total idiot n00bs who get the better players to defend them while they mass carriers. Because we all know, carriers = instant win (not)

Fucking teamstacker, let's all go for him....

Teamstack 

When an entire team in an video game all unanimously decides to go in the exact same direction or to the exact same spot.
This normally results in said entire team dying in a pathetic way, and looking really stupid.

Can also be used to refer to group of people that have done this.

Random nerd 1: "Yo bro, wanna teamstack left this game?"
Random slightly less of a nerd 2: "Aight"

Both precede to die to a grenade thrown from around a corner (they did this every round).

There is a teamstack of red guys on the right hand side of the map.
