Stick the bunch

When a few individuals rally together and challenge the remainder of the group to any kind of competition. These individuals are usually badly outnumbered, but feel confident that they will prevail because of a concentration of their skill.

Those challenged with stick the bunch are placed in an awkward situation, wherein appealing against a team of fewer number is lame, winning against a smaller team and feeling good about it is also lame, and losing is super lame and to be considered an extreme case of ownage.
