Similar to a soccer mom, a bar mom is a white middle or upper-middle class woman in her mid-40's to mid-60's who sees her adult children only in bars. During free time she is found at the bar drinking, playing pool, playing darts, or playing poker. A bar mom is the equivalent of a bar rat, but with children.
When playing a game, most notably a video game, a teammate suggests a bad play and/or demands their teammates follow their poor idea which quickly results in the death of the person(s) the play was suggested to. The horrendous play call/decision results in detrimental effects to the individual going along with the call, often resulting in defeat for the play caller's team. The caller of these disastrous ideas usually survives despite barring their teammates from victory.
