A "big penis approach" is something that is strategic and soundly thought-out using objective factual information about any subject that the strategy or the plan might involve, and is opposed with a "small penis approach" which is stupid and nonsensical and often does more harm than good and uses misleading information and kneejerk reactions, and is based on the rationale that Males with a bigger penis are more likely to have higher intelligence or have an impact on society, namely in the reproduction department, and is an important step to understanding basic strategy, along with a good analogy for understanding this being that a "big penis approach" is like a long thick sausage with a big girth, which blows out the "small penis approach," a little corn dog sausage, straight out of the water.

Person #1: "Oh my God, how are you this smart?"
